<!-- uebergabe der Daten mittels einer "umwandlung" von php in JavaScript
auf diese art eher unueblich
-->

<script>
var person_list = <?php echo json_encode($person_list); ?>;

$(document).ready(function() {
  $.each( person_list, function( key, person ) {
    $('#liclass').append("<li>"+  person['fullname'] +"</li" );

  });

// direkte Formatierung der Daten mit php in html
<div id="person_list">
<?php
foreach ($person_list as $person) {
  printf ("<li> %s, %s, %s </li>\n",

Oder die Trennung von Präsentation und Datengenerierung

php, liefert JSON
list-persons-ajax.php
<code>
<?php
require('db.php');
$dbh = get_db();
$person_list = 
  $dbh->query('select fullname, birthdate, country_code from person')
      ->fetch_all(MYSQLI_ASSOC);	  
	  
header('Content-type: application/json');
echo json_encode($person_list); 
</code>

welches dann mit jquery get abgefragt und danach formatiert angezeigt wird
<code>
<html>
<script src="https://code.jquery.com/jquery-2.2.0.min.js"></script>

<div id='liclass'>
</div>
<script>
$(document).ready(function() {
var ret = $.get("/kurs/list-persons-ajax.php")   
  .done(function( person_list) {    
    $.each( person_list, function( key, person ) {
      $('#liclass').append("<li>"+  person['fullname'] +"</li" );
	});  
  });
});
</script>
</html>
