I have a TCP server, written in C++. The server accepts multiple TCP connections and it's able to process then in parallel.
My Apache installation is unable to open more than 1 connection with the server at the same time. If I try to open 2 tabs at the same time, the 2nd one waits for the 1st one to finish and then starts.
BUT, if I run the script from command line/terminal, I am able to open multiple connections.
From the above experiment is clear, the issue is Apache-PHP installation or my PHP code.
The code in question:
<?php
function connect_($message)
{
$port = 13;
$address = "127.0.0.1";//talk to localhost
$response = "";
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if ($socket !== false)
{
$result = socket_connect($socket, $address, $port);
if ($result !== false)
{
socket_write($socket, $message, strlen($message));//send the message
while ($out = socket_read($socket, 2048)) $response .= $out;//get the response
socket_close($socket);//exit
}
}
return $response;
}
echo connect_('hi');
?>
Can anyone please, exaplain how to setup PHP and Apache in linux and windows to fit my needs?
