			0 ignored issues – show Best Practice introduced 2020-01-01 02:01 UTC by Report Bug Copy Issue Report It is not recommended to use PHP's closing tag `?>` in files other than templates. Using a closing tag in PHP files that only contain PHP code is not recommended as you might accidentally add whitespace after the closing tag which would then be output by PHP. This can cause severe problems, for example headers cannot be sent anymore. A simple precaution is to leave off the closing tag as it is not required, and it also has no negative effects whatsoever.
