Search in text files recursively with PHP - Grep

Every linux user knows the power of grep, which saves us hours. Sometimes we need to find a string/word from html-output of a large CMS, but we dont know in which directoty/file is it. PHP-Grep helps us in this situation with searching in all directories/files under given path.
