The PHP community needs a way to uncover the magic going on inside of Zend Opcache. When your paycheck depends on the success and uptime of your app, the last thing you want is a surprise.
Have you ever noticed how you can spend hours reading docs, but without an example or real world case study, you have NO IDEA what the settings actually do?
If you haven't upgraded to 5.5 yet, the APC extension that everyone uses has been deprecated and you HAVE to use the (now open-source) Zend Opcache. Bummer, I know. No one likes change.
