PHP: Socket server interrupted by socket_recv() - php

Question

I am writing PHP socket server, displayed here is error causing portion. I find out socket_recv() is causing problem, it only lets one computer connect. However, if I comment out socket_recv then its working fine. But I have to receive data also in socket server. Help me find out solution. Please also point out any wrong with code. JQuery part is working fine, hence didn't print it here.
<?php
set_time_limit(0);
$host = '172.28.4.5';
$port = 10000;
$null = NULL;
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_set_option($socket, SOL_SOCKET, SO_REUSEADDR, 1);
socket_bind($socket, $host, $port);
socket_listen($socket);
$clients = array($socket);
while(true) {
$new_socket = socket_accept($socket);//Accepting new connection/socket/client if any
$clients[] = $new_socket;//Adding the new client/socket/connection to client array
$header = socket_read($new_socket, 1024);
perform_handshaking($header, $new_socket, $host, $port);
/* If I want to notify if new connection is established**/
socket_getpeername($new_socket, $ip);
$message = "Welcome to WebSocket $ip";
$array = array(
'message' => $message
);
$message = mask(json_encode($array));
write_to_socket($message);
$found = array_search($socket, $clients);
unset($clients["$found"]);
//Going through each client
foreach($clients as $client) {
//Getting messages with loop how many packages for each client has
while(socket_recv($client, $buf, 1024, 0) >= 1) {
$array = json_decode(unmask($buf));
print_r($array);
}
}
}
}
?>

Answer 1

it seems that
the code is wrong
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_set_option($socket, SOL_SOCKET, SO_REUSEADDR, 1);
socket_bind($socket, $host, $port);
socket_listen($socket);
//$clients = array($socket); <---- here
while(true) {
it seems that you add the listened socket to array , you should not receive and data from the listened socket.
