Hi all Is it possible to have a function with two parameters but and then check if one is passed before using it. In this code here I want to remove spaces and change to lowercase. If the $extra parameter is set I want to add that to the end of the string. function className($nametoUse, $extra){ $noSpace = str_replace(' ', '', $nametoUse); $toLower = strtolower($noSpace); if(!empty($extra)){ $classtoUse = $toLower." ".$extra; }else{ $classtoUse = $toLower; } return $classtoUse; }
