Question

I have 2 PHP scripts, one residing on Server A and another on server B. I need to pass variables received via POST by PHP A to PHP B without the page redirecting. How can I do that?

Answer 1

You can use curl,

$curlHandler = curl_init();

    $curlOpts = array(
            CURLOPT_URL => "http://www.example.com/Target.php",
            CURLOPT_FRESH_CONNECT => true,
            CURLOPT_HEADER => false,
            CURLOPT_POSTFIELDS => http_build_query($_POST, "", "&"),
            CURLOPT_RETURNTRANSFER => true,
            CURLOPT_USERAGENT => "MyScript/0.1"
             );
     curl_setopt_array($curlHandler, $curlOpts);

     if (false===($responseString=curl_exec($curlHandler))) {

           exit("0 - No connection to server.");
     }

    echo $responseString;

If you send POST-Data to this scrip it will send it to http://www.example.com/Target.php.

If it gets $_POST["Foo"] = 10 then it will send $_POST["foo"] = 10 to Target.php.
It uses all Post variables it gets with the same names and values.

EDIT:

If you want to send some vars you can do it like this:

$vars = array("key" => "value", 
              "key2" => "value2",
              ...
             );

after doing so you have to change the line from the example above:

CURLOPT_POSTFIELDS => http_build_query($_POST, "", "&"),

needs to be changed to

CURLOPT_POSTFIELDS => http_build_query($vars, "", "&"),
