PHP Sockets - can't connect -

i trying make php script, following things:

• starts listening on designated port connections , messages
• connects designated port, communication

this how looks (i copy parts of script, because spans multiple classes, , hard copy each part):

constructor main object in script

//connecting designated port communication $this->nodeserver = socket_create(af_inet, sock_stream, sol_tcp); socket_set_option($this->nodeserver, sol_socket, so_reuseaddr, 1);  if (socket_connect($this->nodeserver,"xxx.xxx.xxx.xxx",'14000') === false) {     throw new unexpectedvalueexception("failed connect: " . socket_strerror(socket_late_error()));     exit; }  //starting listen on designated port $this->socketlistener = socket_create(af_inet, sock_stream, sol_tcp); socket_set_option($this->socketlistener, sol_socket, so_reuseaddr, 1); socket_bind($this->socketlistener, 0, $this->listeningport); socket_listen($this->socketlistener);  //adding these 2 sockets(the connected one, , listener one) array $this->addsocket($this->nodeserver); $this->addsocket($this->socketlistener); 

in main file, following:

main file

$connectedtonode=true;  while ($connectedtonode) {     //manage multipal connections     $changedread = $phpworker->socketlist;     $changedwrite = $phpworker->socketlist;     socket_select($changedread, $changedwrite, $null, 0, 10);      echo 'this test echo'; // echo nr. 1     //check new socket     if (in_array($phpworker->socketlistener, $changedread)) {         $socket_new = socket_accept($phpworker->socketlistener); //accpet new socket         $phpworker->addsocket($socket_new); //add socket client array          $header = socket_read($socket_new, 1024); //read data sent socket         socket_getpeername($socket_new, $ip); //get ip address of connected socket         echo "someone connected"; // echo nr. 2         echo $ip; // echo nr. 3          //make room new socket         $found_socket = array_search($phpworker->socketlistener, $changedread);         unset($changedread[$found_socket]);     }      foreach ($changedread $changed_socket) {          //if incomming message, process         while(socket_recv($changed_socket, $buf, 1024, 0) >= 1)         {             echo "this second test"; // echo nr. 4             $socketid = array_search($changed_socket, $phpworker->socketlist);             $phpworker->processmessage($socketid, $buf);         }          $buf = @socket_read($changed_socket, 1024, php_normal_read);         if ($buf === false) { // check disconnected client             // remove client array             $socketid = array_search($changed_socket, $phpworker->socketlist);             if (($socketid==0) || ($socketid==1)) {                 //the first element "nodeserver", second element listener, if either 1 goes away, stop script                 $connectedtonode=false;             }              //unset disconnected client             unset($phpworker->socketlist[$socketid]);             unset($phpworker->socketdata[$socketid]);         }     } } 

i managed connect "nodeserver", , able communicate it, , works fine, can't manage connect php script, listener of php script.

this how tried (another part object):

$this->phphelper = socket_create(af_inet, sock_stream, sol_tcp); socket_set_option($this->phphelper, sol_socket, so_reuseaddr, 1); $hostip=gethostbyname('myhost.name.here'); if (!socket_connect($this->phphelper, $hostip, $portonwhichmainsocketislistening)) {     echo socket_strerror(socket_last_error());     socket_clear_error();     $this->phphelper=null; } else {     socket_send($this->phphelper, "test\0", strlen("test\0"), 0); } 

the echoes in while cycle, there test, , strangely, echo nr 1 fired once, nr.2 , nr.3 never fired, , nr.4 fired each time when send message nodeserver listener php script.

what problem? doing wrong? shouldn't first echo fire @ every loop?

part of script written inspiration page: http://www.phpbuilder.com/articles/application-architecture/optimization/creating-real-time-applications-with-php-and-websockets.html

edit: okay, seems found solution, still don't understand why works:

in while part of below code:

foreach ($changedread $changed_socket) {      //if incomming message, process     while(socket_recv($changed_socket, $buf, 1024, 0) >= 1)     {         echo "this second test"; // echo nr. 4         ...     } } 

i've inserted break 2; command, gives permission main while cycle, continue executing. way, can connect listener socket other php file, , echo's fire. question then, why execution stuck in inner while , for cycles without break command?
