Removing array index reference when using json_encode()

Question

I have made a small application using jQuery\'s datepicker. I am setting unavailable dates to it from a JSON file which looks like this:

{ \"dat         


        

Answer 1

You are ignoring the return value of array_values in your existing attempt to reindex the array. Correct is

$arr['dates'] = array_values($arr['dates']);

The reindexing should also be moved outside the foreach loop, there is no point in reindexing multiple times.
