How can the PHP short-hand notation <?= be used and what are the potential pitfalls when short_open_tags are disabled?

To use the PHP short-hand notation <?=, you can simply echo out a variable or value without using the traditional <?php echo syntax. However, if short_open_tags are disabled in the PHP configuration, the <?= notation will not work and can cause syntax errors in your code. To avoid this issue, you can use the full <?php echo syntax instead. 

&lt;?php
// Using full &lt;?php echo syntax
$name = &quot;John&quot;;
echo $name;

// Using &lt;?= notation (not recommended if short_open_tags are disabled)
// &lt;?= $name;
?&gt;
