In all files of phpMyAdmin source code, closing tag (?>) is included at the end of file. Most frameworks like zend or symfony or laravel suggest to omit closing tag to prevent accidental output of whites paces. In some situations  output may send headers which makes the application incapable to control response headers.

My question is: Is there any specific reason for doing so? 

secondly: Can we omit closing tags at the end of file?
