PHP: get_magic_quotes_gpc

get_magic_quotes_gpc

(PHP 3 >= 3.0.6, PHP 4, PHP 5)

get_magic_quotes_gpc -- Gets the current configuration setting of magic quotes gpc

Description

int get_magic_quotes_gpc ( void )

Returns the current configuration setting of magic_quotes_gpc (0 for off, 1 for on).

注: If the directive magic_quotes_sybase is ON it will completely override magic_quotes_gpc. So even when get_magic_quotes_gpc() returns TRUE neither double quotes, backslashes or NUL's will be escaped. Only single quotes will be escaped. In this case they'll look like: ''

Keep in mind that the setting magic_quotes_gpc will not work at runtime.

例子 1. get_magic_quotes_gpc() example
