Have you searched first???
Try reading through some of these posts (http://www.webdeveloper.com/forum/search.php?searchid=1072959), I'm sure you will find your answer.

//get the entire contents of a file
$contents = file_get_contents($filename);

//determine whether the string ($find) is anywhere in the file
//strpos() finds the position of a string ($find) inside of another string ($contents)
//if it is not found, it will return false
if (strpos($contents, $find)===false) {
//do something if string isn't in file
} else {
//do something if string *is* in file
}

And if you need case-insensitive searching, replace strpos() with stripos().

Dude, it's Saturday night, Final 4 on TV, and you want a response after only 20 minutes - on a thread that's marked as resolved?

How about starting a new thread since it's a new question (and this one is resolved). I'll lock this thread so potential responses don't get spread between threads.
