Using array_chunk on multi array

Question

I have a multi dimensional array and i am now sure how to use array chunk on my array key request while preserving the information into the new array. I would like to split the array every 2 arrays. I tried using array_chunk inside of a loop but no luck.

Here is my array.

This is the array I would like.

This is my code.

$drivers = [];

        foreach($recs as $val => $rec) {
            $drivers[$rec->driver_id]['first_name'] = $rec->first_name;
            $drivers[$rec->driver_id]['patient_first_name'] = $rec->patient_first_name;
            $drivers[$rec->driver_id]['trip_date'] = $rec->trip_date;
            $drivers[$rec->driver_id]['request'][] = $rec;
        }

        foreach($drivers as $val => $driver) {
            $drivers = array_chunk($driver['request'], 2);
        }

Any suggestions?

...sorry, \I had to go away just after commenting on your now-deleted question. I am happy to see that you got array_chunk() to work. It is the best tool for the job. (this question is written much better/clearer than your earlier post) — mickmackusa

Why, in your script, does it look like ypu can access driver_id as an object property, but $rec doesn't have driver_id (it has client_id). Is client_id what you are grouping on? Then batching every two requests per group? — mickmackusa

Using array-chunk if what you need. Check the following example (I remove some of the data to simplify):

$request = array(["id" => 46], ["id" => 49], ["id" => 55], ["id" => 59], ["id" => 69], ["id" => 175], ["id" => 195], ["id" => 197]);
$arr[] = array("first_name" => "Richard", "request" => $request);
foreach($arr as $driver) {
    $requests = array_chunk($driver['request'], 2);
    foreach($requests as $chunck) {
        $ans[] = array("id" => $driver["first_name"], "request" => $chunck); // here you  can add all the other data you need from the "driver" object
    }
}

Now , $ans will have your desire output

That was only example - you can ignore the first 2 line of my code and use your array

Get 'request' from the source array, chunk it and add rest items to each element of the result array

$res = array_chunk($recs['request'], 2);
unset($recs['request']);

foreach($res as &$x)  {
   $x += $recs;
}

$drivers would the source I made some changes but I am getting an error back saying expects parameter 1, the function clearly does have a value. $res = array_chunk($drivers['request'], 2); unset($drivers['request']); foreach($res as &$x) { $x += $drivers; }
