Can CI accept a variable as the full join syntax? [SOLVED]

I created a model which supports a generic database GET request and if you include data from the $joinArray then it will loop through the values of this array and create $builder->join($joinArray);

Unfortunately I can't get this to work.

To keep it short I would like to do the following:

Code:

    $joinData = array(
        0 => "'table AS k', 'k.something = j.anotherthing', 'left'"
    );

    if(isset($joinData)){
        foreach($joinData as $key => $value){
            $builder->join($value);
        }
    }

In the end, it should behave like this:
     $builder->join('table AS k', 'k.something = j.anotherthing', 'left');

thank you for your time!
