PHP and session variable substitution

Hmm, interesting, I would have thought the PHP and APM process the page at the same time or that APM ran first and then PHP second so that you have the full power of server side logic at your disposal.

I want to be able to tell where the login page came from an external system so I'm using a query string to identify the original system. I want to use this to display a success or failure message on the banner of my login page.

This can be done client side in JavaScript, but logically it's easier to write in PHP when the HTML can be turned on or off. I'll just get with my JavaScript development team to write up the necessary code.

Thanks for the prompt replies.
