get_magic_quotes_gpc

(PHP 4, PHP 5)

get_magic_quotes_gpcGets the current configuration setting of magic quotes gpc

说明

int get_magic_quotes_gpc ( void )

Returns the current configuration setting of magic_quotes_gpc

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

For more information about magic_quotes, see this security section.

返回值

Returns 0 if magic quotes gpc are off, 1 otherwise.

范例

Example #1 get_magic_quotes_gpc() example

<?php
echo get_magic_quotes_gpc();         // 1
echo $_POST['lastname'];             // O\'reilly
echo addslashes($_POST['lastname']); // O\\\'reilly

if (!get_magic_quotes_gpc()) {
    
$lastname addslashes($_POST['lastname']);
} else {
    
$lastname $_POST['lastname'];
}

echo 
$lastname// O\'reilly
$sql "INSERT INTO lastnames (lastname) VALUES ('$lastname')";
?>

注释

Note: 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: ''
