Since I am developing and deploying on *nix, shell commands are fine with me.

        $myfile = file ( '/path/to/myfile.txt');
        $count = count ($myfile);

However, sometimes it fails with the following error:

      PHP Fatal error:  Allowed memory size of xxxx bytes exhausted (tried

to allocate 35 bytes) in /path/to/myprogram.php on line 16 Line 16 is the first line above. I'm sure there is a better - more memory efficient - way to do this. Any suggestions? Thanks! Frank Schima Foraker Design <http://www.foraker.com> if you want a cross-platform solution (not that i use windows :)) or you dont want to use exec() or related functions look to the stream functions. they support buffered reading, so theorectically a script could read portions of a file and count lines as it read through the portions.

Sounds a little painful. I'll look into it though.
