Why <? =?> Works on one computer, but not on another?

Question

When I write

<?=?>

it doesn’t work on my PC, but it works on another PC !!! Why ??? :( for example:

<?php
$courses = CourseManager::findAll();
?>
<h3>Course List</h3>
<table>
    <tr><th>Name</th></tr>
 <?php   foreach ($courses as $c){
?>
    <tr>
        <td><?=$c->getName()?></td></tr>
  <?php } ?>

</table>

or is it too simple not? :)

<?= expression ?>

This is a shortcut for

<? echo expression ?>

or

<?php
$i ="test";
?>

<h1><?=$i?></h1>

Thanks for your advice:)
