I am working on an a PHP web application and i need to perform some network operations in the request like fetching someone from remote server based on user's request.

Is it possible to simulate asynchronous behavior in PHP given that i have to pass some data to a function and also need output from it.

My code is like:

<?php

     $data1 = processGETandPOST();
     $data2 = processGETandPOST();
     $data3 = processGETandPOST();

     $response1 = makeNetworkCall($data1);
     $response2 = makeNetworkCall($data2);
     $response3 = makeNetworkCall($data3);

     processNetworkResponse($response1);
     processNetworkResponse($response2);
     processNetworkResponse($response3);

     /*HTML and OTHER UI STUFF HERE*/

     exit;
?>

Each network operation takes around 5 seconds to complete adding a total of 15 seconds to the response time of my application given i make 3 requests.

The makeNetworkCall() function just do a HTTP POST request.

The remote server is an 3rd party API so i don't have any control over there.

PS: Please do not answer giving suggestions about AJAX or Other things. I am currently looking if i can do this through PHP may be with an C++ extension or something like that.
