I cannot add a comment, but I think this will work for you, it should be faster then a regex or a loop:

//after you json_encode, before you decode
$str = str_replace(':[]',':null',json_encode($array));

An empty array in JSON is represented by "[]". Sometimes the arrays are parsed as objects, in that case (or as a fallback) you can replace ":{}" too.
