The function comes in a string like 'key1.key2' and an array, it is necessary to return the value to this "address", how can this be done with prettier?

 function arr($arr, $get) { // Магия } echo arr([ 'key1' => [ 'key2' => 123 ] ], 'key1.key2');

     function arr($arr, $get) { $idxs = explode('.', $get); foreach ($idxs as $idx) $arr = $arr[$idx]; return $arr; }
