ID: 28136 Comment by: fakeman at i dot ua Reported By: daniele-dll at yahoo dot it Status: No Feedback Bug Type: Sockets related Operating System: Windows\Linux PHP Version: 5.0.0RC1 New Comment:
You wrote incorrect code a little. You must not check return value of socket_get_option after socket_connect immediately because some operations (like socket creation) take a long time to execute, mostly because they involve talking to another host, which may have an exruciating long timeout on it. You should use socket_select and when select (or related interface) says that the socket is ready for writing, you can call socket_get_option($SOCKET, SOL_SOCKET, SO_ERROR, ...) on it. And now socket_get_option will return with the error socket_connect would have indicated, had it been called in a blocking manner. If the error is 0, the connect succeeded. As you remember socket_select have timeout paramer and this parameter give some time to connect or no socket.

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
