Titled 'PHP How It Works' we see visiting a website likened to ordering a burger. The image shows a woman at a table ordering from a waiter, the waiter visits the kitchen, the waite returns with the burger. "To understand how PHP works, we’re taking you to a restaurant. Think of going online to visit a website like ordering some food. When you enter the site, the web server takes your request and runs the PHP code - like a waiter taking your order to the kitchen. The PHP code searches the site's database and follows a script to prepare the page - like a chef following a recipe to make a meal. When complete, the web server then delivers the page to the browser, and it appears on screen - that’s your waiter bringing you your dish."

It's not a quick or easy fix. The patch is a 10000 line nightmare. No really it's actually 10k. A lot of that is test code, but there are also significant changes to deep engine internals.

PHP did really really bad memory limit handling. Now it's only really bad.
