I just tried this code:

```
<?php
set_time_limit(0);

$address = '176.9.117.136';
$port = 9000;

$sock = socket_create(AF_INET, SOCK_STREAM, 0);
socket_bind($sock, $address, $port) or die('Could not bind to address');

while(1)
{
    socket_listen($sock);
    $client = socket_accept($sock);

    $input = socket_read($client, 1024);
    echo $input;

    $output = 'URL: http://ip-of-my-server:9000/
HTTP/1.1 200 OK
Date: Tue, 10 Jul 2012 16:58:23 GMT

';
    socket_write($client, $output);

    socket_close($client);
}

socket_close($sock);
?>

```

But there is a problem. Instead of using the content of $output as the headers, Apache returns its own headers...

I don't know why because I execute the script via this command: `php webserv.php`.

However it practically works, because when I load the page `http://ip-of-my-server:9000/` from my browser, it shows me the headers sent by the client on the server, and returns the content of `$output` to the client (my browser).

I want to create my own webserver only in PHP if it's possible. I just want to know how to run it without Apache, so I can manage my own HTTP headers.
