When $result parameter of mysql_fetch_row isn't resource, mysql_fetch_row returns NULL instead of FALSE.

This code:

while (($data = mysql_fetch_row($result)) !== false) {

gets in infinite loop

Test script:
$result = mysql_query("BAD SQL SYNTAX OR CONNECTION PROBLEM"); 
// $result value is now FALSE

$data = mysql_fetch_row($result);

Expected result:

Actual result:
