get_magic_quotes_gpc

Returns the current configuration setting of magic_quotes_gpc

Keep in mind that attempting to set magic_quotes_gpc at runtime will not work.

For more information about magic_quotes, see this security section.

Returns 0 if magic_quotes_gpc is off, 1 otherwise. Or always returns FALSE as of PHP 5.4.0.

Always returns FALSE because the magic quotes feature was removed from PHP.

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: ''

<?php
// If magic quotes are enabled
echo $_POST['lastname'];             // O\'reilly
echo addslashes($_POST['lastname']); // O\\\'reilly

// Usage across all PHP versions
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')";
?>
