error_reporting(E_ALL);

If you are having a problem getting through the script, you need to track the critical variables that affect branching  just use var_dump() at the points where they are referenced and see what value is in them.

If you cannot post the code then You are not likely to get much help; and I guarantee you that you don't have anything so unques that we have not seen it.  Plus is has zero value if it does not work.

Yes.  Run this script, shown here in its entirety and look for "error_log" in the output.  
<?php phpinfo();

Open in new window


Follow the guidance here:
http://php.net/manual/en/function.error-log.php

it sounds like you might be new to PHP?  If so, this will point you to some good learning resources.
