How can the PHP code snippet provided be improved to ensure compatibility with different browsers, including Internet Explorer?

The issue with the PHP code snippet may arise from the use of shorthand PHP opening tags `<?` which may not be supported in all server configurations, especially in older versions of Internet Explorer. To ensure compatibility with different browsers, including Internet Explorer, it is recommended to use the full PHP opening tag `<?php`.

&lt;?php
// Your PHP code here
