using curl to get part of the html

Hello list, I am writing a php script to fetch a html page and verify its content which generated by a remote cgi program. The special cgi program generates endless content to the http client. Therefore, I need to figure out a solution for curl to fetch part of the html source code(In fact, I only need the first 100 lines of the html source). I tried CURLOPT_TIMEOUT, but when curl_exec() timeouts, it will not return part of the html source it already fetched--actually it returns nothing at all. Is there any way to work around this? #!/usr/bin/php4 -q <?php $url = "http://www.example.com/cgi-bin/large_output.cgi"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($ch, CURLOPT_TIMEOUT, 3); $result = curl_exec($ch); curl_close($ch); echo $result; ?> -- Patrick Hsieh<pahud@ezplay.tv> GnuPG Pubilc Key at http://www.ezplay.tv/~pahud/pahudatezplay.pubkey MD5 checksum: b948362c94655b74b33e859d58b8de91
