What are the differences between using <? and <?php in PHP files, and what are the potential drawbacks of using <? instead of <?php?
Using <?php is the standard way to open a PHP code block in PHP files. However, some older PHP configurations may not recognize <? as the opening tag for PHP code. To ensure compatibility across different PHP setups, it's recommended to always use <?php instead of just <?.
<?php
// Your PHP code goes here
?>
