javascript - AJAX Replace Span String with External Date String -

good morning,

i have livestamp.js on website , external .php file parses date string vatsim data file.

the code php file is:

<?php require_once './vendor/autoload.php';  $logfile = './vendor/skymeyer/vatsimphp/app/logsusers.log';  $vatsim = new \vatsimphp\vatsimdata(); $vatsim->setconfig('cacheonly', true); $vatsim->setconfig('logfile', $logfile);  if ($vatsim->loaddata()) {     $info = $vatsim->getgeneralinfo()->toarray(); echo "{$info['update']}"; } else { echo "cannot load data";  }  ?> 

this code pulling date string external file website:

<script type="text/javascript"> function get_update() {     $.ajax({         type: 'post',         url: 'update.php',         data: {             request: 'true'         },         success: function(reply) {             $('.data-livestamp').html("" + reply + "");         }     }); } $(document).ready(function() {     get_update(); }); </script> 

the livestamp.js code html has this: <span data-livestamp="1454063536"></span>

how can change ajax code either replace example date string data string php file or insert contents of php file in between quotation marks in <span data-livestamp="1454063536"></span> line?

thanks in advance.

    success: function(reply) {         $("[data-livestamp]").data('livestamp', reply)     }
