#43325 [Opn->Fbk]: feof() hangs on UDP stream

ID: 43325 Updated by: jani@php.net Reported By: mertcan at dpozitif dot com -Status: Open +Status: Feedback Bug Type: Streams related Operating System: Centos 5.0 PHP Version: 5.2.5 New Comment: Your script doesn't work because you don't get anything in $response in the first place. So you're passing invalid data around long before feof() is used and the server just sits there propably waiting for more data to be input before it gives any back.. Previous Comments: ------------------------------------------------------------------------ [2007-11-20 09:10:45] mertcan at dpozitif dot com Here is the full program: <?php echo rcon_komut("meta list", "123456", "62.68.207.16", 27015); function rcon_komut($komut, $rcon_pass, $ip, $port) { $response = ""; $msg = "ÿÿÿÿchallenge rcon"; $fp = fsockopen("udp://".$ip,$port, $errno, $errstr); stream_set_blocking($fp, 0); fputs($fp, $msg, strlen($msg)); $response = fgets($fp, 1024); $challenge = substr($response, 19, strlen($response) - 20); $msg="ÿÿÿÿrcon".$challenge."\"".$rcon_pass."\"".$komut.chr(0); fputs($fp, $msg, strlen($msg)); while (!feof($fp)) $response .= fgets($fp, 4096); fclose ($fp); return $response; } ?> ------------------------------------------------------------------------ [2007-11-20 08:44:44] jani@php.net That's still just a piece of the script, a proper test script starts with <?php and ends in ?> and can be just copy'pasted and run.. ------------------------------------------------------------------------ [2007-11-19 17:19:22] mertcan at dpozitif dot com i gave $tanim in function use: function rcon_komut($komut, $rcon_pass, $ip, $port) { $msg = "ÿÿÿÿchallenge rcon"; $fp = fsockopen("udp://".$ip,$port, $errno, $errstr); stream_set_blocking($fp, 0); fputs($fp, $msg, strlen($msg)); $response = fgets($fp, 1024); $challenge = substr($response, 19, strlen($response) - 20); $msg="ÿÿÿÿrcon".$challenge."\"".$rcon_pass."\"".$komut.chr(0); fputs($fp, $msg, strlen($msg)); while (!feof($fp)) $response .= fgets($fp, 32); fclose ($fp); $response = substr($response, 6, strlen($response)-6); return $response; } ------------------------------------------------------------------------ [2007-11-19 16:31:10] jani@php.net Well, can you give a script that has some possibility of working properly? In the give script you have at least one variable which is not set anywhere: $komut ------------------------------------------------------------------------ [2007-11-19 14:56:21] mertcan at dpozitif dot com It still hangs: $fp = fsockopen("udp://".$ip,$port, $errno, $errstr); stream_set_blocking($fp, 0); ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
