Hey there while trying to use your great script in a project I got an error while processing a page

Deprecated: strtolower(): Passing null to parameter #1 ($string) of type string is deprecated in....class/PHPCheckstyle.php line 3377

I noticed function names, class names all as default is set to null

$this->_currentClassname = null;

Fix is replacing null with empty string ""

$this->_currentFunctionName = ""; $this->_currentClassname = ""; $this->_currentInterfacename = ""; $this->_currentFilename = ""; $this->_packageName = "";
