1.2.521. Hash Will Use Objects

The ext/hash extension used resources, and is being upgraded to use resources.

<?php

// Post 7.2 code
    $hash = hash_init('sha256');
    if (!is_object($hash)) {
        trigger_error('error');
    }
    hash_update($hash, $message);

// Pre-7.2 code
    $hash = hash_init('md5');
    if (!is_resource($hash)) {
        trigger_error('error');
    }
    hash_update($hash, $message);

?>
