[Gllug] OT: reading from a socket in php

[salsaman at xs4all.nl]

Hi all,
I am trying to write a simple php application which reads from udp port
9998/localhost. I know the data is being sent, but php never receives
anything.

The code i am trying is something like:



function get_response($status_sock)
{

   do {
     // tried also with PHP_NORMAL_READ
     $recv = socket_read($status_sock, '1024',PHP_BINARY_READ);

     // i have also tried:
     //$from='';
     //$port=0;

     // socket_recvfrom($status_sock,$recv,1,0,$from,$port);

     // tried also with socket_read()

     if ($recv != "") {
        // never reaches here...
        echo("got $recv\n");
        return;
     }
     usleep(10000);
   } while ($recv=="");

}

if(($status_sock = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP)) < 0) {
           	echo "Could not create status socket.\n";
}

if (!socket_connect($status_sock,"127.0.0.1",9998)) {
	      echo "Could not connect";
}

get_response($status_sock);

socket_close($status_sock);



Why am I not receiveing any data in the socket ?
