yes, u can do that by ajax post method..

$(document).ready(function() { 
$("#btn_url").on('click', function() {
    var video_val = $("#video_url").val(); alert(video_val);
   $.ajax({
      url: 'ajax_file.php',
      data: {duration: video_val},
      type: 'POST',
      success: function(data) {
          alert(data);
      }
   });
});
});

And in ajax_file.php write below code..

<?php
$duration = $_POST['video_val'];
return $duration ;
?>

You can use Ajax for this solution. When you place your PHP getYoutubeDurationV3 function in a .php file.

$(document).ready(function() { 
$("#btn_url").on('click', function() {
    var video_val = $("#video_url").val(); alert(video_val);
   $.ajax({
      url: 'yourphpscript.php',
      data: {duration: video_val},
      type: 'POST',
      success: function(data) {
          alert(data);
      }
   });
});
});

And in your PHP file you can get the value like this:

<?php
$duration = $_POST['video_val'];

//rest of your logic, in your case your function

//return your response back to your webpage.
return $response;
?>
