Related introduction :

php.ini This file must be named 'php.ini' and placed in the directory specified by the PHPiniDir directive in httpd.conf. It can be viewed using the phpinfo() function. If no modifications are made, it is generally placed in the PHP installation directory under the Windows platform.

The syntax of this file is very simple. Whitespace characters and lines starting with semicolons are simply ignored.

Section titles (eg: [php]) are also simply ignored, even though they may have some meaning in the future.

The format of the setting command is as follows:

directive = value

The command name (directive) is case-sensitive! So "foo=bar" is different from "FOO=bar".

Value (value) can be:

1. A string delimited by quotation marks (such as: "foo")

2. A number (integer or floating point number, Such as: 0, 1, 34, -1, 33.55)

3. A PHP constant (such as: E_ALL, M_PI)

4. An INI constant (On, Off, none)

5. An expression (such as: E_ALL & ~E_NOTICE)

The expression in the INI file only uses: bit operators, logical NOT, parentheses:

| Bit OR

& Bit AND

~ Bit NOT

! Logical NOT

Boolean flag uses On to indicate on and Off to indicate off.

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 dynamic expansion (PHP extension) in the directive value or Zend extension), then you can only use these constants after loading the command line of these dynamic extensions.
