Timeout works only if add stream_set_timeout() to the inloop stream. Why the fsokopen timeout doesnt timeout ? no idea. -------------------------------- This echo "connected," and hangs for ever, timout doesnt works : --------------------------------- $scfp=fsockopen("www.microsoft.com", 111,&$errno,&$errstr,5); if(!$scfp) {echo "error"; exit; } else { echo "connected,"; fputs($scfp,"GET /admin.cgi\r\n\r\n"); while(!feof($scfp)) {$page .= fgets($scfp); } fclose($scfp); ////////////////////// This works, considering timout is checked in the fgets loop. stream_set_timeout() replace the bug of fsockopen that doesnt timeout. $scfp=fsockopen("www.microsoft.com", 111,&$errno,&$errstr,2); if(!$scfp) {echo "error"; exit; } else { echo "connected,"; stream_set_timeout($scfp,2); fputs($scfp,"GET /admin.cgi\r\n\r\n"); while(!feof($scfp)) {$page .= fgets($scfp); $info = stream_get_meta_data($scfp); if ($info['timed_out']) { echo "timeout"; exit; } } fclose($scfp); --------------------- PHP 5.1.1-1.dotdeb.2 (cli) (built: Dec 1 2005 12:46:40) ------------------------------------------------------------------------ [2006-01-31 04:40:13] ipmax at freesurf dot fr we are talking here of a fsockopen connection attempt to a non responding remote server, like a server with DROP iptable firewall. Noteven responding error or 404, just not responding at all. fsockopen never timeout, fgets never find the EOF. => Hang. ------------------------------------------------------------------------ [2006-01-31 04:33:20] ipmax at freesurf dot fr This echo "connected," and hangs for ever, timout doesnt works : --------------------------------- $scfp=fsockopen("www.microsoft.com", 111,&$errno,&$errstr,5); if(!$scfp) {echo "error"; exit; } else { echo "connected,"; stream_set_timeout($scfp,2); fputs($scfp,"GET /admin.cgi\r\n\r\n"); while(!feof($scfp)) {$page .= fgets($scfp); } fclose($scfp); ////////////////////// This works, considering timout is checked in the fgets loop. stream_set_timeout() replace the bug of fsockopen that doesnt timeout. $scfp=fsockopen("www.microsoft.com", 111,&$errno,&$errstr,2); if(!$scfp) {echo "error"; exit; } else { echo "connected,"; stream_set_timeout($scfp,2); fputs($scfp,"GET /admin.cgi\r\n\r\n"); while(!feof($scfp)) {$page .= fgets($scfp); $info = stream_get_meta_data($scfp); if ($info['timed_out']) { echo "timeout"; exit; } } fclose($scfp); --------------------- PHP 5.1.1-1.dotdeb.2 (cli) (built: Dec 1 2005 12:46:40) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
