Re: How to jump to line number in large file

fseek($handle, 1, SEEK_CUR); // or fseek($handle, $pos) $t = fgetc($handle); This probably won't help you, but given a quick glance, it looks like you're incrementing the file pointer by 2 positions on each iteration of your while loop. The fgetc() function returns the character at the current position and increments the file pointer by 1. I haven't tried this, but perhaps using strpos would be faster? Use strpos to seek to find the first "\n", then use the offset parameter to seek to the second, and so on, until strpos() returns false. --GREG
