XMPP和PHP流

Question

im creating a website which uses php to connect to an XMPP server , and send a message However, im having a problem with sending/receiving messages .. Question is do i have to reconnect and send username/password everytime i make a request ( send a message ) ? how to avoid reconnecting ?

This is how i connect :

    $this->_socket = fsockopen("sever.tld", 5222, $errno, $errstr, 30);

i send messages using fwrite Like this :

    fwrite($Socket, $data);

i read messages using fread Like this :

    $response = @fread($this->_socket, 1024);

The approach you're using is not going to work in the long run.

Because a PHP instance effectively ceases to exist when it's finished sending a page back to the browser client, the connection you make to the XMPP server is closed. This means that all state (TLS session, authentication, &c) is lost.

So yes, if you do it this way, you'd have to reconnect and re-authenticate on every page load.

Please don't do it this way. You may use an XMPP-server-side adapter such as XMPP over BOSH, designed for this purpose, or an HTTP-server-side persistent connection via some daemon or longer-lived process which your PHP instances share.
