It looks like you're hading in the right direction. You've grabbed an array of each file. Then cycle through that array and read data from each file. The fread function will allow you to pull data from each file line by line, so you can store each line in an array. Using your idea of pseudo-code: $data = array(); $i = 1; foreach ( file ) { $n = 1; fp = fopen while ($line = fread() ){ $data[$i][$n] = $line; } } foreach ($data as $key => $line ) { foreach ($line as $line_number => $ip) { // do stuff } } -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
