How can the use of short tags impact the portability and compatibility of PHP scripts across different servers?

Using short tags in PHP scripts can impact portability and compatibility across different servers because short tags might not be enabled on all servers by default. To ensure compatibility, it's recommended to use the full `<?php ?>` tags instead of short tags `<? ?>` in your PHP scripts.

// Instead of using short tags
&lt;? echo &quot;Hello, World!&quot;; ?&gt;

// Use full PHP tags for better compatibility
&lt;?php echo &quot;Hello, World!&quot;; ?&gt;
