1[PHP] 2 3;;;;;;;;;;;;;;;;;;; 4; About php.ini ; 5;;;;;;;;;;;;;;;;;;; 6; PHP's initialization file, generally called php.ini, is responsible for 7; configuring many of the aspects of PHP's behavior. 8 9; PHP attempts to find and load this configuration from a number of locations. 10; The following is a summary of its search order: 11; 1. SAPI module specific location. 12; 2. The PHPRC environment variable. (As of PHP 5.2.0) 13; 3. A number of predefined registry keys on Windows (As of PHP 5.2.0) 14; 4. Current working directory (except CLI) 15; 5. The web server's directory (for SAPI modules), or directory of PHP 16; (otherwise in Windows) 17; 6. The directory from the --with-config-file-path compile time option, or the 18; Windows directory (usually C:\windows) 19; See the PHP docs for more specific information. 20; http://php.net/configuration.file 21 22; The syntax of the file is extremely simple. Whitespace and lines 23; beginning with a semicolon are silently ignored (as you probably guessed). 24; Section headers (e.g. [Foo]) are also silently ignored, even though 25; they might mean something in the future. 26 27; Directives following the section heading [PATH=/www/mysite] only 28; apply to PHP files in the /www/mysite directory. Directives 29; following the section heading [HOST=www.example.com] only apply to 30; PHP files served from www.example.com. Directives set in these 31; special sections cannot be overridden by user-defined INI files or 32; at runtime. Currently, [PATH=] and [HOST=] sections only work under 33; CGI/FastCGI. 34; http://php.net/ini.sections 35 36; Directives are specified using the following syntax: 37; directive = value 38; Directive names are *case sensitive* - foo=bar is different from FOO=bar. 39; Directives are variables used to configure PHP or PHP extensions. 40; There is no name validation. If PHP can't find an expected 41; directive because it is not set or is mistyped, a default value will be used. 42 43; The value can be a string, a number, a PHP constant (e.g. E_ALL or M_PI), one 44; of the INI constants (On, Off, True, False, Yes, No and None) or an expression 45; (e.g. E_ALL & ~E_NOTICE), a quoted string ("bar"), or a reference to a 46; previously set variable or directive (e.g. ${foo}) 47 48; Expressions in the INI file are limited to bitwise operators and parentheses: 49; | bitwise OR 50; ^ bitwise XOR 51; & bitwise AND 52; ~ bitwise NOT 53; ! boolean NOT 54 55; Boolean flags can be turned on using the values 1, On, True or Yes. 56; They can be turned off using the values 0, Off, False or No. 57 58; An empty string can be denoted by simply not writing anything after the equal 59; sign, or by using the None keyword: 60 61; foo = ; sets foo to an empty string 62; foo = None ; sets foo to an empty string 63; foo = "None" ; sets foo to the string 'None' 64 65; If you use constants in your value, and these constants belong to a 66; dynamically loaded extension (either a PHP extension or a Zend extension), 67; you may only use these constants *after* the line that loads the extension. 68 69;;;;;;;;;;;;;;;;;;; 70; About this file ; 71;;;;;;;;;;;;;;;;;;; 72; PHP comes packaged with two INI files. One that is recommended to be used 73; in production environments and one that is recommended to be used in 74; development environments. 75 76; php.ini-production contains settings which hold security, performance and 77; best practices at its core. But please be aware, these settings may break 78; compatibility with older or less security conscience applications. We 79; recommending using the production ini in production and testing environments. 80 81; php.ini-development is very similar to its production variant, except it is 82; much more verbose when it comes to errors. We recommend using the 83; development version only in development environments, as errors shown to 84; application users can inadvertently leak otherwise secure information. 85 86; This is the php.ini-production INI file. 87 88;;;;;;;;;;;;;;;;;;; 89; Quick Reference ; 90;;;;;;;;;;;;;;;;;;; 91 92; The following are all the settings which are different in either the production 93; or development versions of the INIs with respect to PHP's default behavior. 94; Please see the actual settings later in the document for more details as to why 95; we recommend these changes in PHP's behavior. 96 97; display_errors 98; Default Value: On 99; Development Value: On 100; Production Value: Off 101 102; display_startup_errors 103; Default Value: On 104; Development Value: On 105; Production Value: Off 106 107; error_reporting 108; Default Value: E_ALL 109; Development Value: E_ALL 110; Production Value: E_ALL & ~E_DEPRECATED & ~E_STRICT 111 112; log_errors 113; Default Value: Off 114; Development Value: On 115; Production Value: On 116 117; max_input_time 118; Default Value: -1 (Unlimited) 119; Development Value: 60 (60 seconds) 120; Production Value: 60 (60 seconds) 121 122; output_buffering 123; Default Value: Off 124; Development Value: 4096 125; Production Value: 4096 126 127; register_argc_argv 128; Default Value: On 129; Development Value: Off 130; Production Value: Off 131 132; request_order 133; Default Value: None 134; Development Value: "GP" 135; Production Value: "GP" 136 137; session.gc_divisor 138; Default Value: 100 139; Development Value: 1000 140; Production Value: 1000 141 142; session.sid_bits_per_character 143; Default Value: 4 144; Development Value: 5 145; Production Value: 5 146 147; short_open_tag 148; Default Value: On 149; Development Value: Off 150; Production Value: Off 151 152; variables_order 153; Default Value: "EGPCS" 154; Development Value: "GPCS" 155; Production Value: "GPCS" 156 157; zend.exception_ignore_args 158; Default Value: Off 159; Development Value: Off 160; Production Value: On 161 162; zend.exception_string_param_max_len 163; Default Value: 15 164; Development Value: 15 165; Production Value: 0 166 167;;;;;;;;;;;;;;;;;;;; 168; php.ini Options ; 169;;;;;;;;;;;;;;;;;;;; 170; Name for user-defined php.ini (.htaccess) files. Default is ".user.ini" 171;user_ini.filename = ".user.ini" 172 173; To disable this feature set this option to an empty value 174;user_ini.filename = 175 176; TTL for user-defined php.ini files (time-to-live) in seconds. Default is 300 seconds (5 minutes) 177;user_ini.cache_ttl = 300 178 179;;;;;;;;;;;;;;;;;;;; 180; Language Options ; 181;;;;;;;;;;;;;;;;;;;; 182 183; Enable the PHP scripting language engine under Apache. 184; http://php.net/engine 185engine = On 186 187; This directive determines whether or not PHP will recognize code between 188; <? and ?> tags as PHP source which should be processed as such. It is 189; generally recommended that <?php and ?> should be used and that this feature 190; should be disabled, as enabling it may result in issues when generating XML 191; documents, however this remains supported for backward compatibility reasons. 192; Note that this directive does not control the <?= shorthand tag, which can be 193; used regardless of this directive. 194; Default Value: On 195; Development Value: Off 196; Production Value: Off 197; http://php.net/short-open-tag 198short_open_tag = Off 199 200; The number of significant digits displayed in floating point numbers. 201; http://php.net/precision 202precision = 14 203 204; Output buffering is a mechanism for controlling how much output data 205; (excluding headers and cookies) PHP should keep internally before pushing that 206; data to the client. If your application's output exceeds this setting, PHP 207; will send that data in chunks of roughly the size you specify. 208; Turning on this setting and managing its maximum buffer size can yield some 209; interesting side-effects depending on your application and web server. 210; You may be able to send headers and cookies after you've already sent output 211; through print or echo. You also may see performance benefits if your server is 212; emitting less packets due to buffered output versus PHP streaming the output 213; as it gets it. On production servers, 4096 bytes is a good setting for performance 214; reasons. 215; Note: Output buffering can also be controlled via Output Buffering Control 216; functions. 217; Possible Values: 218; On = Enabled and buffer is unlimited. (Use with caution) 219; Off = Disabled 220; Integer = Enables the buffer and sets its maximum size in bytes. 221; Note: This directive is hardcoded to Off for the CLI SAPI 222; Default Value: Off 223; Development Value: 4096 224; Production Value: 4096 225; http://php.net/output-buffering 226output_buffering = 4096 227 228; You can redirect all of the output of your scripts to a function. For 229; example, if you set output_handler to "mb_output_handler", character 230; encoding will be transparently converted to the specified encoding. 231; Setting any output handler automatically turns on output buffering. 232; Note: People who wrote portable scripts should not depend on this ini 233; directive. Instead, explicitly set the output handler using ob_start(). 234; Using this ini directive may cause problems unless you know what script 235; is doing. 236; Note: You cannot use both "mb_output_handler" with "ob_iconv_handler" 237; and you cannot use both "ob_gzhandler" and "zlib.output_compression". 238; Note: output_handler must be empty if this is set 'On' !!!! 239; Instead you must use zlib.output_handler. 240; http://php.net/output-handler 241;output_handler = 242 243; URL rewriter function rewrites URL on the fly by using 244; output buffer. You can set target tags by this configuration. 245; "form" tag is special tag. It will add hidden input tag to pass values. 246; Refer to session.trans_sid_tags for usage. 247; Default Value: "form=" 248; Development Value: "form=" 249; Production Value: "form=" 250;url_rewriter.tags 251 252; URL rewriter will not rewrite absolute URL nor form by default. To enable 253; absolute URL rewrite, allowed hosts must be defined at RUNTIME. 254; Refer to session.trans_sid_hosts for more details. 255; Default Value: "" 256; Development Value: "" 257; Production Value: "" 258;url_rewriter.hosts 259 260; Transparent output compression using the zlib library 261; Valid values for this option are 'off', 'on', or a specific buffer size 262; to be used for compression (default is 4KB) 263; Note: Resulting chunk size may vary due to nature of compression. PHP 264; outputs chunks that are few hundreds bytes each as a result of 265; compression. If you prefer a larger chunk size for better 266; performance, enable output_buffering in addition. 267; Note: You need to use zlib.output_handler instead of the standard 268; output_handler, or otherwise the output will be corrupted. 269; http://php.net/zlib.output-compression 270zlib.output_compression = Off 271 272; http://php.net/zlib.output-compression-level 273;zlib.output_compression_level = -1 274 275; You cannot specify additional output handlers if zlib.output_compression 276; is activated here. This setting does the same as output_handler but in 277; a different order. 278; http://php.net/zlib.output-handler 279;zlib.output_handler = 280 281; Implicit flush tells PHP to tell the output layer to flush itself 282; automatically after every output block. This is equivalent to calling the 283; PHP function flush() after each and every call to print() or echo() and each 284; and every HTML block. Turning this option on has serious performance 285; implications and is generally recommended for debugging purposes only. 286; http://php.net/implicit-flush 287; Note: This directive is hardcoded to On for the CLI SAPI 288implicit_flush = Off 289 290; The unserialize callback function will be called (with the undefined class' 291; name as parameter), if the unserializer finds an undefined class 292; which should be instantiated. A warning appears if the specified function is 293; not defined, or if the function doesn't include/implement the missing class. 294; So only set this entry, if you really want to implement such a 295; callback-function. 296unserialize_callback_func = 297 298; The unserialize_max_depth specifies the default depth limit for unserialized 299; structures. Setting the depth limit too high may result in stack overflows 300; during unserialization. The unserialize_max_depth ini setting can be 301; overridden by the max_depth option on individual unserialize() calls. 302; A value of 0 disables the depth limit. 303;unserialize_max_depth = 4096 304 305; When floats & doubles are serialized, store serialize_precision significant 306; digits after the floating point. The default value ensures that when floats 307; are decoded with unserialize, the data will remain the same. 308; The value is also used for json_encode when encoding double values. 309; If -1 is used, then dtoa mode 0 is used which automatically select the best 310; precision. 311serialize_precision = -1 312 313; open_basedir, if set, limits all file operations to the defined directory 314; and below. This directive makes most sense if used in a per-directory 315; or per-virtualhost web server configuration file. 316; Note: disables the realpath cache 317; http://php.net/open-basedir 318;open_basedir = 319 320; This directive allows you to disable certain functions. 321; It receives a comma-delimited list of function names. 322; http://php.net/disable-functions 323disable_functions = 324 325; This directive allows you to disable certain classes. 326; It receives a comma-delimited list of class names. 327; http://php.net/disable-classes 328disable_classes = 329 330; Colors for Syntax Highlighting mode. Anything that's acceptable in 331; <span style="color: ???????"> would work. 332; http://php.net/syntax-highlighting 333;highlight.string = #DD0000 334;highlight.comment = #FF9900 335;highlight.keyword = #007700 336;highlight.default = #0000BB 337;highlight.html = #000000 338 339; If enabled, the request will be allowed to complete even if the user aborts 340; the request. Consider enabling it if executing long requests, which may end up 341; being interrupted by the user or a browser timing out. PHP's default behavior 342; is to disable this feature. 343; http://php.net/ignore-user-abort 344;ignore_user_abort = On 345 346; Determines the size of the realpath cache to be used by PHP. This value should 347; be increased on systems where PHP opens many files to reflect the quantity of 348; the file operations performed. 349; Note: if open_basedir is set, the cache is disabled 350; http://php.net/realpath-cache-size 351;realpath_cache_size = 4096k 352 353; Duration of time, in seconds for which to cache realpath information for a given 354; file or directory. For systems with rarely changing files, consider increasing this 355; value. 356; http://php.net/realpath-cache-ttl 357;realpath_cache_ttl = 120 358 359; Enables or disables the circular reference collector. 360; http://php.net/zend.enable-gc 361zend.enable_gc = On 362 363; If enabled, scripts may be written in encodings that are incompatible with 364; the scanner. CP936, Big5, CP949 and Shift_JIS are the examples of such 365; encodings. To use this feature, mbstring extension must be enabled. 366;zend.multibyte = Off 367 368; Allows to set the default encoding for the scripts. This value will be used 369; unless "declare(encoding=...)" directive appears at the top of the script. 370; Only affects if zend.multibyte is set. 371;zend.script_encoding = 372 373; Allows to include or exclude arguments from stack traces generated for exceptions. 374; In production, it is recommended to turn this setting on to prohibit the output 375; of sensitive information in stack traces 376; Default Value: Off 377; Development Value: Off 378; Production Value: On 379zend.exception_ignore_args = On 380 381; Allows setting the maximum string length in an argument of a stringified stack trace 382; to a value between 0 and 1000000. 383; This has no effect when zend.exception_ignore_args is enabled. 384; Default Value: 15 385; Development Value: 15 386; Production Value: 0 387; In production, it is recommended to set this to 0 to reduce the output 388; of sensitive information in stack traces. 389zend.exception_string_param_max_len = 0 390 391;;;;;;;;;;;;;;;;; 392; Miscellaneous ; 393;;;;;;;;;;;;;;;;; 394 395; Decides whether PHP may expose the fact that it is installed on the server 396; (e.g. by adding its signature to the Web server header). It is no security 397; threat in any way, but it makes it possible to determine whether you use PHP 398; on your server or not. 399; http://php.net/expose-php 400expose_php = On 401 402;;;;;;;;;;;;;;;;;;; 403; Resource Limits ; 404;;;;;;;;;;;;;;;;;;; 405 406; Maximum execution time of each script, in seconds 407; http://php.net/max-execution-time 408; Note: This directive is hardcoded to 0 for the CLI SAPI 409max_execution_time = 30 410 411; Maximum amount of time each script may spend parsing request data. It's a good 412; idea to limit this time on productions servers in order to eliminate unexpectedly 413; long running scripts. 414; Note: This directive is hardcoded to -1 for the CLI SAPI 415; Default Value: -1 (Unlimited) 416; Development Value: 60 (60 seconds) 417; Production Value: 60 (60 seconds) 418; http://php.net/max-input-time 419max_input_time = 60 420 421; Maximum input variable nesting level 422; http://php.net/max-input-nesting-level 423;max_input_nesting_level = 64 424 425; How many GET/POST/COOKIE input variables may be accepted 426;max_input_vars = 1000 427 428; Maximum amount of memory a script may consume 429; http://php.net/memory-limit 430memory_limit = 128M 431 432;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; 433; Error handling and logging ; 434;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; 435 436; This directive informs PHP of which errors, warnings and notices you would like 437; it to take action for. The recommended way of setting values for this 438; directive is through the use of the error level constants and bitwise 439; operators. The error level constants are below here for convenience as well as 440; some common settings and their meanings. 441; By default, PHP is set to take action on all errors, notices and warnings EXCEPT 442; those related to E_NOTICE and E_STRICT, which together cover best practices and 443; recommended coding standards in PHP. For performance reasons, this is the 444; recommend error reporting setting. Your production server shouldn't be wasting 445; resources complaining about best practices and coding standards. That's what 446; development servers and development settings are for. 447; Note: The php.ini-development file has this setting as E_ALL. This 448; means it pretty much reports everything which is exactly what you want during 449; development and early testing. 450; 451; Error Level Constants: 452; E_ALL - All errors and warnings (includes E_STRICT as of PHP 5.4.0) 453; E_ERROR - fatal run-time errors 454; E_RECOVERABLE_ERROR - almost fatal run-time errors 455; E_WARNING - run-time warnings (non-fatal errors) 456; E_PARSE - compile-time parse errors 457; E_NOTICE - run-time notices (these are warnings which often result 458; from a bug in your code, but it's possible that it was 459; intentional (e.g., using an uninitialized variable and 460; relying on the fact it is automatically initialized to an 461; empty string) 462; E_STRICT - run-time notices, enable to have PHP suggest changes 463; to your code which will ensure the best interoperability 464; and forward compatibility of your code 465; E_CORE_ERROR - fatal errors that occur during PHP's initial startup 466; E_CORE_WARNING - warnings (non-fatal errors) that occur during PHP's 467; initial startup 468; E_COMPILE_ERROR - fatal compile-time errors 469; E_COMPILE_WARNING - compile-time warnings (non-fatal errors) 470; E_USER_ERROR - user-generated error message 471; E_USER_WARNING - user-generated warning message 472; E_USER_NOTICE - user-generated notice message 473; E_DEPRECATED - warn about code that will not work in future versions 474; of PHP 475; E_USER_DEPRECATED - user-generated deprecation warnings 476; 477; Common Values: 478; E_ALL (Show all errors, warnings and notices including coding standards.) 479; E_ALL & ~E_NOTICE (Show all errors, except for notices) 480; E_ALL & ~E_NOTICE & ~E_STRICT (Show all errors, except for notices and coding standards warnings.) 481; E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR (Show only errors) 482; Default Value: E_ALL 483; Development Value: E_ALL 484; Production Value: E_ALL & ~E_DEPRECATED & ~E_STRICT 485; http://php.net/error-reporting 486error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT 487 488; This directive controls whether or not and where PHP will output errors, 489; notices and warnings too. Error output is very useful during development, but 490; it could be very dangerous in production environments. Depending on the code 491; which is triggering the error, sensitive information could potentially leak 492; out of your application such as database usernames and passwords or worse. 493; For production environments, we recommend logging errors rather than 494; sending them to STDOUT. 495; Possible Values: 496; Off = Do not display any errors 497; stderr = Display errors to STDERR (affects only CGI/CLI binaries!) 498; On or stdout = Display errors to STDOUT 499; Default Value: On 500; Development Value: On 501; Production Value: Off 502; http://php.net/display-errors 503display_errors = Off 504 505; The display of errors which occur during PHP's startup sequence are handled 506; separately from display_errors. We strongly recommend you set this to 'off' 507; for production servers to avoid leaking configuration details. 508; Default Value: On 509; Development Value: On 510; Production Value: Off 511; http://php.net/display-startup-errors 512display_startup_errors = Off 513 514; Besides displaying errors, PHP can also log errors to locations such as a 515; server-specific log, STDERR, or a location specified by the error_log 516; directive found below. While errors should not be displayed on productions 517; servers they should still be monitored and logging is a great way to do that. 518; Default Value: Off 519; Development Value: On 520; Production Value: On 521; http://php.net/log-errors 522log_errors = On 523 524; Set maximum length of log_errors. In error_log information about the source is 525; added. The default is 1024 and 0 allows to not apply any maximum length at all. 526; http://php.net/log-errors-max-len 527log_errors_max_len = 1024 528 529; Do not log repeated messages. Repeated errors must occur in same file on same 530; line unless ignore_repeated_source is set true. 531; http://php.net/ignore-repeated-errors 532ignore_repeated_errors = Off 533 534; Ignore source of message when ignoring repeated messages. When this setting 535; is On you will not log errors with repeated messages from different files or 536; source lines. 537; http://php.net/ignore-repeated-source 538ignore_repeated_source = Off 539 540; If this parameter is set to Off, then memory leaks will not be shown (on 541; stdout or in the log). This is only effective in a debug compile, and if 542; error reporting includes E_WARNING in the allowed list 543; http://php.net/report-memleaks 544report_memleaks = On 545 546; This setting is off by default. 547;report_zend_debug = 0 548 549; Turn off normal error reporting and emit XML-RPC error XML 550; http://php.net/xmlrpc-errors 551;xmlrpc_errors = 0 552 553; An XML-RPC faultCode 554;xmlrpc_error_number = 0 555 556; When PHP displays or logs an error, it has the capability of formatting the 557; error message as HTML for easier reading. This directive controls whether 558; the error message is formatted as HTML or not. 559; Note: This directive is hardcoded to Off for the CLI SAPI 560; http://php.net/html-errors 561;html_errors = On 562 563; If html_errors is set to On *and* docref_root is not empty, then PHP 564; produces clickable error messages that direct to a page describing the error 565; or function causing the error in detail. 566; You can download a copy of the PHP manual from http://php.net/docs 567; and change docref_root to the base URL of your local copy including the 568; leading '/'. You must also specify the file extension being used including 569; the dot. PHP's default behavior is to leave these settings empty, in which 570; case no links to documentation are generated. 571; Note: Never use this feature for production boxes. 572; http://php.net/docref-root 573; Examples 574;docref_root = "/phpmanual/" 575 576; http://php.net/docref-ext 577;docref_ext = .html 578 579; String to output before an error message. PHP's default behavior is to leave 580; this setting blank. 581; http://php.net/error-prepend-string 582; Example: 583;error_prepend_string = "<span style='color: #ff0000'>" 584 585; String to output after an error message. PHP's default behavior is to leave 586; this setting blank. 587; http://php.net/error-append-string 588; Example: 589;error_append_string = "</span>" 590 591; Log errors to specified file.

G,P,C,E & S are abbreviations for the following respective super 643; globals: GET, POST, COOKIE, ENV and SERVER. There is a performance penalty 644; paid for the registration of these arrays and because ENV is not as commonly 645; used as the others, ENV is not recommended on productions servers.

These arrays are extremely 671; useful when running scripts from the command line. When this directive is 672; enabled, registering these variables consumes CPU cycles and memory each time 673; a script is executed.
