What key do you want to change, and what is the logic behind why and how it will change? — Mike Brant, Oct 08 '14 at 13:55
@MikeBrant Brant i am using json_encode to encode array and output is not what i wants suppose my result is 'code' {"0":["Monday","5:30 PM"],"1":["Friday","6:00 PM"],"3":["Tuesday","4:15 PM"],"4":["Wednesday","8:30 PM"],"5":["Thursday","1:45 PM"] 'code' and this is what i wants 'code' [{"label":"Monday","5:30 PM"},"label":{"Friday","6:00 PM"},"label":{"Tuesday","4:15 PM"},"label":{"Wednesday","8:30 PM"},"label":{"Thursday","1:45 PM"}] 'code' — Rachit Gupta, Oct 08 '14 at 13:58

If you're looking to replace a key based on the value, you could use this code: (assuming you want to replace Array[4])

<?php

foreach ($array as $key => $value) {
    if ($value == "5") {
        $array['new_key'] = $value;
        unset($array[$key]));
    }
}

If you want to define a specific key, you only have to say so:

<?php

$array['new_key'] = 'some_value';
