php.ini
- [PHP]
- ;;;;;;;;;;;
- ; WARNING ;
- ;;;;;;;;;;;
- ; This is the default settings file for new PHP installations.
- ; By default, PHP installs itself with a configuration suitable for
- ; development purposes, and *NOT* for production purposes.
- ; For several security-oriented considerations that should be taken
- ; before going online with your site, please consult php.ini-recommended
- ; and http://php.net/manual/en/security.php.
- ;;;;;;;;;;;;;;;;;;;
- ; About php.ini ;
- ;;;;;;;;;;;;;;;;;;;
- ; This file controls many aspects of PHP's behavior. In order for PHP to
- ; read it, it must be named 'php.ini'. PHP looks for it in the current
- ; working directory, in the path designated by the environment variable
- ; PHPRC, and in the path that was defined in compile time (in that order).
- ; Under Windows, the compile-time path is the Windows directory. The
- ; path in which the php.ini file is looked for can be overridden using
- ; the -c argument in command line mode.
- ;
- ; The syntax of the file is extremely simple. Whitespace and Lines
- ; beginning with a semicolon are silently ignored (as you probably guessed).
- ; Section headers (e.g. [Foo]) are also silently ignored, even though
- ; they might mean something in the future.
- ;
- ; Directives are specified using the following syntax:
- ; directive = value
- ; Directive names are *case sensitive* - foo=bar is different from FOO=bar.
- ;
- ; The value can be a string, a number, a PHP constant (e.g. E_ALL or M_PI), one
- ; of the INI constants (On, Off, True, False, Yes, No and None) or an expression
- ; (e.g. E_ALL & ~E_NOTICE), or a quoted string ("foo").
- ;
- ; Expressions in the INI file are limited to bitwise operators and parentheses:
- ; | bitwise OR
- ; & bitwise AND
- ; ~ bitwise NOT
- ; ! boolean NOT
- ;
- ; Boolean flags can be turned on using the values 1, On, True or Yes.
- ; They can be turned off using the values 0, Off, False or No.
- ;
- ; An empty string can be denoted by simply not writing anything after the equal
- ; sign, or by using the None keyword:
- ;
- ; foo = ; sets foo to an empty string
- ; foo = none ; sets foo to an empty string
- ; foo = "none" ; sets foo to the string 'none'
- ;
- ; If you use constants in your value, and these constants belong to a
- ; dynamically loaded extension (either a PHP extension or a Zend extension),
- ; you may only use these constants *after* the line that loads the extension.
- ;

- ; About this file ;
- ;;;;;;;;;;;;;;;;;;;
- ; All the values in the php.ini-dist file correspond to the builtin
- ; defaults (that is, if no php.ini is used, or if you delete these lines,
- ; the builtin defaults will be identical).

- ; Language Options ;
- ;;;;;;;;;;;;;;;;;;;;
- ; Enable the PHP scripting language engine under Apache.
- engine = On
- ; Enable compatibility mode with Zend Engine 1 (PHP 4.x)
- zend.ze1_compatibility_mode = Off
- ; Allow the <? tag. Otherwise, only <?php and <script> tags are recognized.
- ; NOTE: Using short tags should be avoided when developing applications or
- ; libraries that are meant for redistribution, or deployment on PHP
- ; servers which are not under your control, because short tags may not
- ; be supported on the target server. For portable, redistributable code,
- ; be sure not to use short tags.
- short_open_tag = On
- ; Allow ASP-style <% %> tags.

- y2k_compliance = On
- ; Output buffering allows you to send header lines (including cookies) even
- ; after you send body content, at the price of slowing PHP's output layer a
- ; bit. You can enable output buffering during runtime by calling the output
- ; buffering functions. You can also enable output buffering for all files by
- ; setting this directive to On. If you wish to limit the size of the buffer
- ; to a certain size - you can use a maximum number of bytes instead of 'On', as
- ; a value for this directive (e.g., output_buffering=4096).
