What is the potential issue with using short open tags in PHP code?

Using short open tags in PHP code can lead to compatibility issues with servers that do not have short open tags enabled. To ensure maximum compatibility, it is recommended to use the full `<?php` tag instead. This can easily be achieved by updating your PHP code to use the full opening tag `<?php` instead of the short `<?`.

&lt;?php
// Code goes here
