Question

I have a form on one page with the action set to /process.php

Within the process.php I have the validation of the form and also it writes to a database on the server

Answer 1

Example using curl:

$name = 'Test';
$email = 'test@gmail.com';

$ch = curl_init(); // initialize curl handle
$url = "http://domain2.com/process.php"; 
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_FAILONERROR, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 10); // times out after 10s
curl_setopt($ch, CURLOPT_POST, 1); // set POST method
curl_setopt($ch, CURLOPT_POSTFIELDS, "text=$name&name=$email"); // post fields
$data = curl_exec($ch); // run the whole process
curl_close($ch);

Answer 2

you can use file_get_contents for the same.

Example:

$name="foobar";
$messge="blabla";

$postdata = http_build_query(
    array(
        'name' => $name,
        'message' => $message
    )
);

$opts = array('http' =>
    array(
        'method'  => 'POST',
        'header'  => 'Content-type: application/x-www-form-urlencoded',
        'content' => $postdata
    )
);

$context  = stream_context_create($opts);

$result = @file_get_contents('http://yourdomain.com/process_request.php', false, $context);

 if($http_response_header[0]=="HTTP/1.1 404 Not Found"):

            echo "iam 404";

 elseif($http_response_header[0]=="HTTP/1.1 200 OK"):

            echo "iam 200";

 else:

            echo "unknown error"; 

 endif;
