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()) {
    
$lastname stripslashes($_POST['lastname']);
}
else {
    
$lastname $_POST['lastname'];
}

// If using MySQL
$lastname mysql_real_escape_string($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: ''
