In a new submission from cosmo from CodeFetch.com notes that their search engine can now search PHP code, examples, and publicated materials.

Search (you can even use a few regular expressions) for PHP source code snippets from dozens of books -- you'll get syntax highlighted examples written by PHP experts, and links to the related docs at PHP.net. No advertising other than the blurb for the book that answered your query.

Even just a search for the word 'test' returned tons of results from all sorts of sources - incluidng references to several books.

It's a nice start in the PHP search area - already added to my bookmark list...
