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