How to put the time and date on a logout PHP script -

i'm wondering if there's way of putting date , time on php script when user logs out, displays along lines of you logged out on 19/04/2016 @ 11:00am. php script have

<?php  // include function files application require_once('bookmark_fns.php'); session_start(); $old_user = $_session['valid_user'];  // store  test if *were* logged in unset($_session['valid_user']); $result_dest = session_destroy();  // start output html do_html_header('logging out');  if (!empty($old_user)) {   if ($result_dest)  {     // if logged in , logged out     echo 'logged out.<br />';     do_html_url('login.php', 'login');   } else {     // logged in , not logged out     echo 'could not log out.<br />';   } } else {   // if weren't logged in came page somehow   echo 'you not logged in, , have not been logged out.<br />';   do_html_url('login.php', 'login'); }  do_html_footer();  ?> 

with date function it's easy :

$date = date("d/m/y"); $time = date("h:ia"); echo "you logged out on $date @ $time"; // return logged out on 19/04/2016 @ 02:59am
