how to make array like this

Question

I have an array in the array, and I want to make it just one array, and I can easily retrieve that data i have some like this

but the coding only combines the last value in the first array, not all values

is it possible to make it like that? so that I can take arrays easily

this is not a php array. Are you need a conversion in php or js — prasanth, Apr 29 '19 at 06:26

no duplicate, this is different, and if it's the same I am still confused about applying it in my case. this helps but only the last value joins https://3v4l.org/uo6kZ — Futra Player, Apr 29 '19 at 07:04
@FutraPlayer You edited your original question, which was slightly different. Now it's an exact duplicate though. So edit it back with your actual data (simplified), because the linked question does solve your current issue. — Jeto, Apr 29 '19 at 07:12

Use array_merge (doc) and ... (which break array to separate arrays):

function flatten($arr) {
    return array_merge(...$arr);
}

$arr = [[["AAA", "BBB"]], [["CCC"]]];
$arr = flatten(flatten($arr)); // using twice as you have double depth

In your case, $arr is $obj["test2"]. If your object is json cast it to array first and if it is a string use json_decode

I would make use of the unpacking operator ..., combined with array_merge:

$array['test2'] = array_merge(...array_merge(...$array['test2']));

In your case you need to flatten exactly twice, if you try to do it one time too much it will fail due to the items being actual arrays themselves (from PHP's perspective).

your answer works, but only combines the last value in the first array, not all values – Futra Player Apr 29 '19 at 06:51
@dWinder I didn't notice your answer, sorry about that. Let me upvote it at least. – Jeto Apr 29 '19 at 08:27
@FutraPlayer You should probably accept dWinder's answer instead, who posted the same solution earlier. – Jeto Apr 29 '19 at 08:38

if you have a array then you can use the below code

if(!empty($array['test2'])){
    $newarray = array();

    foreach ($array['test2'] as $arrayRow) {
        $newarray = array_merge($newarray,$arrayRow);
    }

    $array['test2'] = $newarray;
}
