Dynamic array keys

Question

I have a string like this:

$string = \'one/two/three/four\';

which I turn it into a array:

$keys = explode(\'/\', $string);

Answer 1

    $arr['one']['two']['three']['four'] = 'value';

    $string = 'one/two/three/four';
    $ExpCheck = explode("/", $string);
    $CheckVal = $arr;
    foreach($ExpCheck AS $eVal){
        $CheckVal = $CheckVal[$eVal]??false;
        if (!$CheckVal)
            break;
    }
    if ($CheckVal) {
        $val =$CheckVal;
    }

this will give u your value in array.
