infinite loop problem

hi, I'm using preg_match for pattern matching and am trying to search a large file. The following code if (preg_match ("/wcb/,$myFile,$matches)) { do this } results in an infinite loop. The file never ends! Is there a way when reading a file in to set an EOF marker? Or is there another way to set a flag with preg_match at the EOF? thanks! Maria Maria B.
