• Name: PHP
• Keyword: p
• Address: http://www.php.net/search.php
• Query string: pattern=%s&show=quickref

You have to check “Use POST” to be able to type in a query string.

Click OK, and then click Ok.

From now on you will be able to search the PHP function list by typing “p function” in the address bar. You can change “quickref” to “all” if you want to search all php.net sites, or “manual” for the online documentation.

Enjoy! I orignally picked this tip up from PHP.net, don’t know the exact URL tho.
