unused two elements classname and function operation Phpstorm return this error
it doesn't return any echo
I don't know if outside or inside the class if I pass one param to the function operation
I don't know how to use classname i suppose is outside from the class classname

class classname{
    public $attribute;
    function operation($param){
        $this->attribute = $param;
        echo $this->attribute;
    }
}

i don't know if it is correct if have this code outside the class classname

$a = new classname;
$a->operation(12);

    Works for me from the command line:

    $ php -a
Interactive shell

php > class classname{
php {     public $attribute;
php {     function operation($param){
php {         $this->attribute = $param;
php {         echo $this->attribute;
php {     }
php { }
php >
php > $a = new classname;
php > $a->operation(12);
12
php >

    Don't know if we're seeing the whole story, though? 🤷
