You can use this if you want to get&set array values dynamically.

function getVal($data,$chain){
    $level = $data;
    for($i=0;$i

How it works:

Calling getVal($data,array('foo','bar','2017-08')) will return the equivalent of $data['foo']['bar']['2017-08'].

Calling setVal($data,array('foo','bar','2017-08'),'hello') will set value as if you called $data['foo']['bar']['2017-08'] = 'hello'. non-existent keys will be created automatically by php magic.

This can be useful if you want to build the structure of the array dynamically.
