ID: 28136 Updated by: sniper@php.net Reported By: daniele-dll at yahoo dot it -Status: Open +Status: Feedback Bug Type: Sockets related Operating System: Windows\Linux PHP Version: 5.0.0RC1 New Comment: Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If possible, make the script source available online and provide an URL to it here. Try to avoid embedding huge scripts into the report. Also try the latest CVS snapshot from http://snaps.php.net/ Previous Comments: ------------------------------------------------------------------------ [2004-07-10 00:43:48] snodge at custard dot org Hi - I have the same issue, althought I am using PHP 5.0RC3 (cli) from Linux. Here is some of the code that I am using - I added an echo statement so that I could see what was happening when I connected with more than one client at a time: $port = 5000; if (!$sock = socket_create_listen($port)) { echo socket_strerror(socket_last_error()); } if (!socket_set_option($sock, SOL_SOCKET, SO_REUSEADDR, 1)) { echo socket_strerror(socket_last_error()); } if (!socket_set_nonblock($sock)) { echo socket_strerror(socket_last_error()); } while (true) { $msgsock == FALSE; do { @$msgsock = socket_accept($sock); } while ($msgsock == FALSE); echo "Received connection from $msgsock\n"; ------------------------------------------------------------------------ [2004-04-24 16:56:04] daniele-dll at yahoo dot it Description: ------------ Hi to all i'm tring to write a little application with PHP using Socket, the external module, not fsockopen function or similar. I've noticed that, with this, and previous version of php, that after i create a socket and set it as non blocking socket, when i try to connect using socket_get_option($SOCKET, SOL_SOCKET, SO_ERROR) i recive EVER 0 Instead i should recive 115 If socket_get_option, with these params, return 0, it mean that connection is done and i can send datas, but if i send datas i get a warning that say that socket is in a connection state so i can't send datas. There is some parts of code: $this->socket[$sock_id]['resource'] = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); if (!is_resource($this->socket[$sock_id]['resource'])) die("Unable to create socket! " . socket_strerror(socket_last_error()) . "\r\n"); if (!socket_set_option($this->socket[$sock_id]['resource'], SOL_SOCKET, SO_REUSEADDR, 1)) { die("Unable to set to as REUSABLE socket! " . socket_strerror(socket_last_error($this->socket[$sock_id]['resource'])) . "\r\n"); after i set socket as reusable (but php gimme me the same problem without this line too) and, after, if i need, i bind socket to a specific IP and PORT after there is this code: @socket_connect($this->socket[$sock_id]['resource'], $this->socket[$sock_id]['remote_host'], $this->socket[$sock_id]['remote_port']); while (($ris = @socket_get_option($this->socket[$sock_id]['resource'], SOL_SOCKET, SO_ERROR)) == 115) { echo "--> " . $ris . "\r\n"; } echo "\r\n--> " . $ris . "\r\n"; If you run this code it will exit immedatly printing: --> 0 Infact, after, if you try to write to socket, you will get a warning I haven't modified php.ini, and i've tried to run this code, using only socket extension, on windows and on linux I use apache 1.3.29 on windows and on linux bye ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28136&edit=1
