6c3fcaf1dSJohannes Schlüter; PHP's initialization file, generally called php.ini, is responsible for
7c3fcaf1dSJohannes Schlüter; configuring many of the aspects of PHP's behavior.
8c3fcaf1dSJohannes Schlüter
9c3fcaf1dSJohannes Schlüter; PHP attempts to find and load this configuration from a number of locations.
10c3fcaf1dSJohannes Schlüter; The following is a summary of its search order:
11c3fcaf1dSJohannes Schlüter; 1. SAPI module specific location.
12c3fcaf1dSJohannes Schlüter; 2. The PHPRC environment variable. (As of PHP 5.2.0)
13c3fcaf1dSJohannes Schlüter; 3. A number of predefined registry keys on Windows (As of PHP 5.2.0)
14c3fcaf1dSJohannes Schlüter; 4. Current working directory (except CLI)
15c3fcaf1dSJohannes Schlüter; 5. The web server's directory (for SAPI modules), or directory of PHP
16c3fcaf1dSJohannes Schlüter; (otherwise in Windows)
17c3fcaf1dSJohannes Schlüter; 6. The directory from the --with-config-file-path compile time option, or the
1844c5dea9SKalle Sommer Nielsen; Windows directory (usually C:\windows)
19c3fcaf1dSJohannes Schlüter; See the PHP docs for more specific information.
20c1ccccc6SPhilip Olson; http://php.net/configuration.file
21c3fcaf1dSJohannes Schlüter
22710021d1SJohannes Schlüter; The syntax of the file is extremely simple.  Whitespace and lines
23c3fcaf1dSJohannes Schlüter; beginning with a semicolon are silently ignored (as you probably guessed).
24c3fcaf1dSJohannes Schlüter; Section headers (e.g. [Foo]) are also silently ignored, even though
2584dcca9fSLukas Smith; they might mean something in the future.
26e0669bf1SEric Stewart
27e0669bf1SEric Stewart; Directives following the section heading [PATH=/www/mysite] only
28e0669bf1SEric Stewart; apply to PHP files in the /www/mysite directory.  Directives
29e0669bf1SEric Stewart; following the section heading [HOST=www.example.com] only apply to
30e0669bf1SEric Stewart; PHP files served from www.example.com.  Directives set in these
31e0669bf1SEric Stewart; special sections cannot be overridden by user-defined INI files or
32e0669bf1SEric Stewart; at runtime. Currently, [PATH=] and [HOST=] sections only work under
33e0669bf1SEric Stewart; CGI/FastCGI.
34c1ccccc6SPhilip Olson; http://php.net/ini.sections
35c3fcaf1dSJohannes Schlüter
36c3fcaf1dSJohannes Schlüter; Directives are specified using the following syntax:
37c3fcaf1dSJohannes Schlüter; directive = value
38c3fcaf1dSJohannes Schlüter; Directive names are *case sensitive* - foo=bar is different from FOO=bar.
39e0669bf1SEric Stewart; Directives are variables used to configure PHP or PHP extensions.
40e0669bf1SEric Stewart; There is no name validation.  If PHP can't find an expected
41e0669bf1SEric Stewart; directive because it is not set or is mistyped, a default value will be used.
42c3fcaf1dSJohannes Schlüter
43c3fcaf1dSJohannes Schlüter; The value can be a string, a number, a PHP constant (e.g. E_ALL or M_PI), one
44c3fcaf1dSJohannes Schlüter; of the INI constants (On, Off, True, False, Yes, No and None) or an expression
45e0669bf1SEric Stewart; (e.g. E_ALL & ~E_NOTICE), a quoted string ("bar"), or a reference to a
46e0669bf1SEric Stewart; previously set variable or directive (e.g. ${foo})
47c3fcaf1dSJohannes Schlüter
48c3fcaf1dSJohannes Schlüter; Expressions in the INI file are limited to bitwise operators and parentheses:
49c3fcaf1dSJohannes Schlüter; |  bitwise OR
50e0669bf1SEric Stewart; ^  bitwise XOR
51c3fcaf1dSJohannes Schlüter; &  bitwise AND
52c3fcaf1dSJohannes Schlüter; ~  bitwise NOT
53c3fcaf1dSJohannes Schlüter; !  boolean NOT
54c3fcaf1dSJohannes Schlüter
55c3fcaf1dSJohannes Schlüter; Boolean flags can be turned on using the values 1, On, True or Yes.
56c3fcaf1dSJohannes Schlüter; They can be turned off using the values 0, Off, False or No.
57c3fcaf1dSJohannes Schlüter
58c3fcaf1dSJohannes Schlüter; An empty string can be denoted by simply not writing anything after the equal
59c3fcaf1dSJohannes Schlüter; sign, or by using the None keyword:
60c3fcaf1dSJohannes Schlüter
61ca21ba3fSsundarchi; foo =         ; sets foo to an empty string
62ca21ba3fSsundarchi; foo = None    ; sets foo to an empty string
63ca21ba3fSsundarchi; foo = "None"  ; sets foo to the string 'None'
64c3fcaf1dSJohannes Schlüter
65c3fcaf1dSJohannes Schlüter; If you use constants in your value, and these constants belong to a
66c3fcaf1dSJohannes Schlüter; dynamically loaded extension (either a PHP extension or a Zend extension),
67c3fcaf1dSJohannes Schlüter; you may only use these constants *after* the line that loads the extension.

72c3fcaf1dSJohannes Schlüter; PHP comes packaged with two INI files. One that is recommended to be used
73c3fcaf1dSJohannes Schlüter; in production environments and one that is recommended to be used in
74c3fcaf1dSJohannes Schlüter; development environments.
75c3fcaf1dSJohannes Schlüter
76c3fcaf1dSJohannes Schlüter; php.ini-production contains settings which hold security, performance and
77c3fcaf1dSJohannes Schlüter; best practices at its core. But please be aware, these settings may break
78c3fcaf1dSJohannes Schlüter; compatibility with older or less security conscience applications. We
79c3fcaf1dSJohannes Schlüter; recommending using the production ini in production and testing environments.
80c3fcaf1dSJohannes Schlüter
81d0727b58SBryan Hanks, PMP; php.ini-development is very similar to its production variant, except it is
82d0727b58SBryan Hanks, PMP; much more verbose when it comes to errors. We recommend using the
83d0727b58SBryan Hanks, PMP; development version only in development environments, as errors shown to
84c3fcaf1dSJohannes Schlüter; application users can inadvertently leak otherwise secure information.
