Hello,
I'm going through The "PHP Bible 2nd Edition" and keep can't seem to get this piece of code working from one of the examples I downloaded. I get a blank page. T tried to add an error script but no luck.
I am running PHP 4.3.2 on my OSX system.
here is the code:
<?php
ini_set ('error_reporting', E_ALL);
// turn on automatic error logging
ini_set('log_errors', true);
// turn off error display
ini_set('display_errors', true);
/******************************************************
* "How geeky are you?" script, showing with screens. *
* Screen 1: : quiz form. Screen 2: results page. *
******************************************************/
// The header which appears in both cases
