Hanging on socket_read

[joseph127]

I am trying to read a response from a socket I have written on a Java application. However the PHP is just hanging. Here is the code I am using to read from the socket:

while($resp = socket_read($socket, 1000)) {
   $str .= $resp;
   if (strpos($str, "\n") !== false) {
        break;
   }
}

When I run the socket call from terminal there is deffinately a response.

Thanks,
