; 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 ;

;;;;;;;;;;;;;;;;;;;

; This is the recommended, PHP 5-style version of the php.ini-dist file. It

; sets some non standard settings, that make PHP more efficient, more secure,

; and encourage cleaner coding.

;

; The price is that with these settings, PHP may be incompatible with some

; applications, and sometimes, more difficult to develop with. Using this

; file is warmly recommended for production sites. As all of the changes from

; the standard settings are thoroughly documented, you can go over each one,

; and decide whether you want to use it or not.

;

; For general information about the php.ini file, please consult the php.ini-dist

; file, included in your PHP distribution.

;

; This file is different from the php.ini-dist file in the fact that it features

; different values for several directives, in order to improve performance, while

; possibly breaking compatibility with the standard out-of-the-box behavior of

; PHP. Please make sure you read what's different, and modify your scripts

; accordingly, if you decide to use this file instead.

;

; - register_globals = Off [Security, Performance]

; Global variables are no longer registered for input data (POST, GET, cookies,

; environment and other server variables). Instead of using $foo, you must use

; you can use $_REQUEST["foo"] (includes any variable that arrives through the

; request, namely, POST, GET and cookie variables), or use one of the specific

; $_GET["foo"], $_POST["foo"], $_COOKIE["foo"] or $_FILES["foo"], depending

; on where the input originates. Also, you can look at the

; import_request_variables() function.

; Note that register_globals is going to be depracated (i.e., turned off by

; default) in the next version of PHP, because it often leads to security bugs.

; Read http://php.net/manual/en/security.registerglobals.php for further

; information.

; - register_long_arrays = Off [Performance]

; Disables registration of the older (and deprecated) long predefined array

; variables ($HTTP_*_VARS). Instead, use the superglobals that were

; introduced in PHP 4.1.0

; - display_errors = Off [Security]

; With this directive set to off, errors that occur during the execution of

; scripts will no longer be displayed as a part of the script output, and thus,

; will no longer be exposed to remote users. With some errors, the error message

; content may expose information about your script, web server, or database

; server that may be exploitable for hacking. Production sites should have this

; directive set to off.

; - log_errors = On [Security]

; This directive complements the above one. Any errors that occur during the

; execution of your script will be logged (typically, to your server's error log,

; but can be configured in several ways). Along with setting display_errors to off,

; this setup gives you the ability to fully understand what may have gone wrong,

; without exposing any sensitive information to remote users.

; - output_buffering = 4096 [Performance]

; Set a 4KB output buffer. Enabling output buffering typically results in less

; writes, and sometimes less packets sent on the wire, which can often lead to

; better performance. The gain this directive actually yields greatly depends

; on which Web server you're working with, and what kind of scripts you're using.

; - register_argc_argv = Off [Performance]

; Disables registration of the somewhat redundant $argv and $argc global

; variables.

; - magic_quotes_gpc = Off [Performance]

; Input data is no longer escaped with slashes so that it can be sent into

; SQL databases without further manipulation. Instead, you should use the

; function addslashes() on each input element you wish
