; PHP is still an evolving tool, and its functions are constantly being deleted
; And the setting changes in php.ini can reflect considerable changes,
; when using the new PHP Before versioning, it would be beneficial to study php.ini

; About this file ;
;;;;; ;;;;;;;;;;;;;;;
; This file controls many aspects of PHP. In order for PHP to read this file, it must be named
; 'php.ini'. PHP will search for the file in these places in sequence: the current working directory; the path specified by the environment variable PHPRC
;; the path specified during compilation.
; Under Windows, the path when compiling is the Windows installation directory.
; In command line mode, the search path of php.ini can be replaced with the -c parameter.
; The syntax of this file is very simple. Whitespace characters and lines starting with a semicolon ';' are simply ignored (as you might
; guess).
Section titles (e.g. [Foo]) are also simply ignored, even though they may
; have some meaning in the future.
;
; directives are specified using the following syntax:
; directive identifier = value
; directive = value
; directive identifiers are *case-sensitive* - foo=bar differs at FOO = bar.
;
; The value can be a string, a number, a PHP constant (such as: E_ALL or M_PI), The
in the INI
constant; a (On, Off, True, False, Yes, No and None), or an expression
; (such as: E_ALL & ~E_NOTICE), or a string enclosed in quotes ("foo").
;
; INI file Expressions are restricted to bitwise operators and parentheses.
; | bitwise OR
; & bitwise AND
; ~ bitwise NOT
; ! boolean NOT
;
; The Boolean flag can be 1, On, True or Yes. These values ​​are placed open status.
; They can be turned off using the values ​​0, Off, False or No.
;
; An empty string can be represented by not writing anything after the equal sign, or using the None keyword:
;
; foo = ; Set foo to an empty string
; foo = none ; Set foo to the empty string
; foo = "none" ; Set foo to the string 'none'
;
; If you use constants in value settings, and these Constants belong to dynamically loaded extension libraries (either PHP extensions, or Zend extensions), and you can only use these constants *after* the lines that load these extensions.
;
; All values ​​set in the php.ini-dist file are the same as the built-in default values ​​(that is, if php.ini
; is not used or you delete them row, the default value is the same).
