How to convert object format to json format in php

Question

I'm using array_unique to remove the duplicate values but it returns an object format.

$event = array_unique($array_event);

output as

{"0":{"title":"new","description":"hai"},"4":null}

Excepted output:

[{"title":"new","description":"hai"},null}]

Can anyone help with this issue?

You shoud reindex result before json_encode

$event = array_values(array_unique($array_event));
