What potential issues can arise from using short tags like <? in PHP code?

Using short tags like <? can lead to compatibility issues with servers that do not have short tags enabled. To ensure maximum compatibility, it is recommended to use the full <?php tag instead. This can easily be done by updating the PHP configuration to allow short tags or by using the full <?php tag throughout the code. 

&lt;?php
// Code using full &lt;?php tag
echo &quot;Hello, World!&quot;;
?&gt;
