Easily search through the WordPress source

If you haven't already heard about the Php Cross Reference for the WordPress source code, or even used it and didn't realize like I had many times before understanding what it was all about, it's an amazing tool provided by Yoast using PHPXref.

Trunk versions of WordPress are updated from SVN every 30 minutes,
In the video below, Joost de Valk, talks about what it can do and how to use and cross reference things in the WordPress source code.

Install the plugins

To make it even easier for you, there are plugins you can install to make searching through code even more convenient for you. There's one for each of the following:

• WordPress Trunk Install Search Plugin
• WordPress 2.9.2 Install Search Plugin
• WordPress MU Trunk Install Search Plugin
• BBPress Trunk Install Search Plugin

Also, if you find this to be a greatly useful tool and have a little extra change laying around, or if you use this tool to make money yourself, you can/should make a donation via Paypal and show your support for this great free service.

That is all for now

Hope this helps you out, and motivates you to kick start your longing desires to learn the WP core once and for all. I know it is something that many people would like to do, but put it off, understandably, as can be a lot to try and take in.

Have fun!
