To this you might also add an MD5 hash to check for authenticity,
depending on what you're doing with that incoming data that you're
unserializing (consider an client who sends you a serialized array that
you didn't intend). You'll also want to encode the serialized data with
htmlentities:
$serialized = serialize($testArray);
$hash = md5($serialized . "my secret phrase");
echo '<input type="hidden" name="serialized" value="'.htmlentities($serialized).'">';
echo '<input type="hidden" name="hash" value="'.$hash.'">';
then on the receiving end:
if ($_POST['hash'] != md5($_POST['serialized'] . "my secret phrase") {
// the hash doesn't match up, consider the data unusable
} else{
$testArray = unserialize($_POST['serialized']);
}
