PHP Socket Server "Broken Pipe" error

[yanjchan]

Hi!

I wrote this as an attempt to create a simple client-server socket chat.

Unfortunately, I keep getting errors about broken pipes.

 

Any help would be much appreciated.

 

#!/usr/local/bin/php -q
<?php
error_reporting(E_ALL);

set_time_limit(0);

ob_implicit_flush(); 

$address = '192.168.1.138';
$port = 31415;


if (($sktMain = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) === false)
{
echo "Failed to create socket.\n";
echo socket_strerror(socket_last_error()) . "\n";
}

socket_set_option($sktMain, SOL_SOCKET,SO_REUSEADDR, 1); 

if (socket_bind($sktMain, $address, $port) === false)
{
echo "Failed to bind to port $port.\n";
echo socket_strerror(socket_last_error()) . "\n";
}

if (socket_listen($sktMain) === false)
{
echo "Failed to start listening on socket.\n";
echo socket_strerror(socket_last_error()) . "\n";
}

$clients = array(array('sock' => $sktMain));

while (true)
{
print_r($clients);

foreach ($clients as $client)
	$read[] = $client['sock'];

$ready = socket_select($read, $write = NULL, $except = NULL, $tv_sec = NULL);

for ($i = 0; $i < count($clients); $i++)
{
	if (in_array($clients[$i]['sock'], $read))
	{
		echo "Was in array\n";
		$socket = $clients[$i]['sock'];

		if ($socket == $sktMain)
		{
			if (($client = socket_accept($sktMain)) < 0)
			{
				echo "Failed to accept socket.\n";
				echo socket_strerror(socket_last_error()) . "\n";
				continue;
			}
			else
			{
				array_push($clients, array('sock' => $client));
			}
		}
		else
		{
			$bytes = socket_recv($socket, $buffer, 2048, 0);

			if ($bytes == null)
			{
				unset($clients[$i]);
				socket_close($socket);
			}
			else
			{
				foreach ($clients as $client)
				{
					if ($client != $sktMain)
						socket_write($client['sock'], $buffer, strlen($buffer));
				}

			}
		}
	}
}
