Socket in php send receive messages through persistent connection - php

Question

I have following scenario:
PHP persistent socket server made it run through console in infinite loop
It is my server.php and running it once by using ' php server.php ' command from command line.
<?php
// set some variables
$host = "127.0.0.1";
$port = 3000;
// don't timeout!
set_time_limit(0);
// create socket
$socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket\n");
// bind socket to port
$result = socket_bind($socket, $host, $port) or die("Could not bind to socket\n");
while(true) {
// start listening for connections
$result = socket_listen($socket, 3) or die("Could not set up socket listener\n");
// accept incoming connections
// spawn another socket to handle communication
$spawn = socket_accept($socket) or die("Could not accept incoming connection\n");
// read client input
$input = socket_read($spawn, 1024) or die("Could not read input\n");
// clean up input string
$input = trim($input);
echo "Client Message : ".$input;
// reverse client input and send back
$output = strrev($input) . "\n";
echo socket_send($spawn, $output, strlen ($output), 0) or die("Could not write output\n");
// close sockets
}
socket_close($spawn);
socket_close($socket);
?>
Client.php here from this file I am sending message to socket server: At this point I am successful to send message to my socket server.
<?php
$host = "127.0.0.1";
$port = 3000;
$message = "Abhi ye sab kaise karen ahm asdasdasdasd";
//echo "Message To server :".$message;
// create socket
$socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket\n");
// connect to server
$result = socket_connect($socket, $host, $port) or die("Could not connect to server\n");
// get server response
//Send the message to the server
if( ! socket_send ( $socket , $message , strlen($message) , 0))
{
$errorcode = socket_last_error();
$errormsg = socket_strerror($errorcode);
die("Could not send data: [$errorcode] $errormsg \n");
} else {
echo "Message send successfully \n".$message;
}
//socket_close($socket);
?>
Receiver.php another file where I want to receive response my socket server is sending which is not working and Its keep on loading with out giving any out put.
<?php
$host = "127.0.0.1";
$port = 3000;
$message = "Abhi ye sab kaise karen ahm ";
//echo "Message To server :".$message;
// create socket
$socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket\n");
// connect to server
$result = socket_connect($socket, $host, $port) or die("Could not connect to server\n");
// get server response
//Send the message to the server
while(true){
$from = '';
$port = 3000;
echo socket_recvfrom($socket, $buf, 12, 0, $from, $port);
echo "Received $buf from remote address $from and remote port $port" . PHP_EOL;
}
//socket_close($socket);
?>
My receiver end is not receiving any out put. I am trying to do this way:
Send message from client to socket server and as soon as socket server dispatch it my receiver end display it, I am successful only up to client where I client.php sending message to server.php but receiver.php is not receiving any thing.
Thanks
