hi i am writing a small application where a user enters a phrase in the textfield and i would like to display all the files present in the root directory which consists of the keyword or keywords entered by the user. i have used a few comparison functions but i am not getting the expected result. $my_file = file_get_contents("filename.html"); what ever the user enters whether it is a single word or few words i would like to compare with $my_file in a case insensitive manner. can anyone suggest the best method and how to go about. thanks.
