How can php indexed array be json_encoded as associative array?

Question

Something like:

[0 => 'a', 1 => 'b']

to json

{
    "0": "a",
    "1": "b",
}

instead of

["a","b"]

Is the array key an incremental value?

This is what you're looking for. Forcing the JSON Object is the only solution you're looking for.

$array = array( '0' => 'a', '1' => 'b', '2' => 'c', '3' => 'c' );
$json = json_encode($array, JSON_FORCE_OBJECT);
echo $json;

Good answer but not entirely solve my problem. I may have arrays in deeper layers.

You can use the JSON_FORCE_OBJECT option:

$array = array(
    0 => 'Banana',
    1 => 'Minions',
    2 => array(
        5 => 'MariaOzawa',
        6 => 'YukiOsawa'
    )
);
$myJsonString = json_encode($MyArray, JSON_FORCE_OBJECT);
print_r($myJsonString);

Then you can see result like this:

{"0":"Banana","1":"Minions","2":{"5":"MariaOzawa","6":"YukiOsawa"}}

With this way, you can keep your array keys whatever how many layers is it into json_object

Hope this help
