I would not expect your code, as you typed it, to do what you expect. I realigned things to make it easier to see what is happening. With what you have, it is very unlikely that you will ever print out a match. You are incrementing your counter for every line of the file, not for every match actually found. Try this code instead: <?php $contents=fread($readfile,100000); $pattern="<a href.*\">"; while(!feof($readfile)) { $contents=fgets($readfile,4065); if(eregi($pattern,$contents,$regs)) { for($i = 0; $i < sizeof($regs); $i++) { echo "$regs[$i]<br>"; } } } ?> -- Jason Stechschulte jpstech@unoh.edu -- I hope I'm not getting so famous that I can't think out load [sic] anymore. -- Larry Wall in <199709032332.QAA21669@wall.org>
