Have you ever shelled into a file system where a bunch of files were executable that should not be? Or maybe permissions are generally a mess?

Typically within a website file system, files should be 644 (owner read/write, group & all just read) and directories should be 755 (owner read/write/execute, group and all just read/execute).

If you don't have any special needs for individual files to be executable, or you just want to start fresh, you can use this method.

I recently installed Zend Server CE on my MacBook Pro to check out the performance of the "partial page" caching Zend offers in their platform.

I was pleasantly surprised how simple it was to get up and running. Zend Platform CE installs its own version of Apache, PHP. If you're installing it on Windows or Mac, it will also install MySQL.

Everything is configured and controlled in your zend path. By default on the Mac it is /usr/local/zend.
