how to search a dir and display a txt file with php ???

[thyscorpion]

hi ???
i have a site in which i want the php code to search a specified dir on my site containing TXT files. The search will be with a search string i give.
i have been till now picking up txt files when i know a file name. but dont know how to search for a file according to a given keyword (or a part of keyword).
Please help me out as soon as possible. as i need the site up and running in 2 days. :-S.
was using something like this:
[code]$filename ="downloadedMovies.txt";   

$myFile = fopen($filename, "r"); //open the file for reading, file pointer will be at the beginning of the file
[/code]
but now i want to use a simple Include command. :-)..
hope someone can help me at the earliest..

you can put all the results into an array, then use array_rand to randomly select a record.

hi thanks..
i needed something like:
if the keyword is: "manic monday"
the script should search for a "manic-monday.txt" and if not found ( no exact matches) . it should get teh next best match example: "manic.txt".
i agree putting them into the array is the right step forward but how to search in this way?

please help me out on this...
