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

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

例 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

注意: 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: ''
