I don't suggest using file_get_contents. It would probably be more
efficient (at least less memory intensive) to use fopen() and fread().
Just be sure you overlap each read by $the_size_of_the_largest
phrase_or_keyword - 1. Then use stripos() for matching... of course that
won't work so well if whitespace doesn't need to match exactly in
phrases. In which case you'll need to resort to other techniques.
