How do I `json_encode()` keys from PHP array?

Question

I have an array which prints like this

Array ( [0] => 1691864 [1] => 7944458 [2] => 9274078 [3] => 1062072 [4] => 8625335 [5] => 8255371 [6         


        

Answer 1

Use this instead:

json_encode((object)$temp)

This converts the array into object, which when JSON-encoded, will display the keys.

If you are storing a sequence of data, not a mapping from number to another number, you really should use array.
