What are the advantages and disadvantages of using short_open_tags in PHP code?

Short open tags in PHP allow developers to use `<?` instead of `<?php` to open PHP code blocks, which can make code more concise and easier to read. However, using short open tags can lead to conflicts with XML declarations and may not be supported on all servers. It is generally recommended to use the full `<?php` tag to ensure compatibility and avoid any potential issues.
