Question

I have an array and a var like this:

$arrPs =array('p1','p2','pN');
$intVar = 80;

Now i want to convert it into an array like this:

array(
   'p1'=>array(
            'p2'=>array(
                'pN'=>$intVar
             )
     )
);

This should work no matter how many values are in $arrPs array.

Hope this makes sense.

function myWalker($input, $last, &$output = array()) {
    if (count($input) > 1) {
        $val = array_shift($input);
        $output[$val] = array();
        myWalker($input, $last, $output[$val]);
    }
    else {
        $output[$input[0]] = $last;
    }

    return $output;
}

$out = myWalker($arrPs, $intVar);
