Recursive search

I noticed the ability to search within directories, although I am a little confused.

I am looking to have it search all *.php files in all sub directories, this is what I have:

$sr = new search_replace($search, '', '*.php');
$sr->set_search_function('quick');
$sr->set_directories(getcwd());
$sr->do_search();

Any tips on that method would be great.

Thank you,

I need the same thing too, need to do recursive search and replace across multiple subdirectories, about 2 levels deep. Need to search all php, js, css. The documentation did not cover it. Any pointer please.

I got as far as find and replace one string. How can I find 2 specific strings and display the number of occurrences of each find without replacing? Also, how can I find and replace multiple strings at the same time and display the number of occurrences of each replacement?
