What is the purpose of short_open_tags in PHP configuration?

Short open tags in PHP allow you to use `<?` instead of `<?php` to open PHP code blocks. However, short open tags can conflict with XML declarations and may not be enabled by default in some PHP configurations. To ensure compatibility and prevent issues, it's recommended to disable short open tags by setting `short_open_tags` to `Off` in your PHP configuration.

// Disable short open tags in PHP configuration
ini_set('short_open_tags', 'Off');
