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: ''
