Using array_chunk on multi array - php

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.
[0] => Array
(
[first_name] => Richard
[patient_first_name] => Donna
[trip_date] => 2018-08-24
[request] => Array
(
[0] => stdClass Object
(
[id] => 46
[client_id] => 9873
[city] => COOLIDGE
[state] => AZ
[zip] => 85228
)
[1] => stdClass Object
(
[id] => 49
[client_id] => 14965
[city] => CHANDLER
[state] => AZ
[zip] => 85226
)
[2] => stdClass Object
(
[id] => 55
[client_id] => 10120
[city] => PHX
[state] => AZ
[zip] => 85008
)
[3] => stdClass Object
(
[id] => 59
[client_id] => 11229
[city] => BUCKEYE
[state] => AZ
[zip] => 85326
)
[4] => stdClass Object
(
[id] => 69
[client_id] => 13769
[city] => PHOENIX
[state] => AZ
[zip] => 85035
)
[5] => stdClass Object
(
[id] => 175
[client_id] => 16437
[city] => Phx
[state] => Az
[zip] => 85029
)
[6] => stdClass Object
(
[id] => 195
[client_id] => 16457
[city] => Apache Junction
[state] => Az
[zip] => 85120
)
[7] => stdClass Object
(
[id] => 197
[client_id] => 16459
[city] => Mesa
[state] => Az
[zip] => 85204
)
)
)
This is the array I would like.
[0] => Array
(
[first_name] => Richard
[patient_first_name] => Donna
[trip_date] => 2018-08-24
[request] => Array
(
[0] => stdClass Object
(
[id] => 46
[client_id] => 9873
[city] => COOLIDGE
[state] => AZ
[zip] => 85228
)
[1] => stdClass Object
(
[id] => 49
[client_id] => 14965
[city] => CHANDLER
[state] => AZ
[zip] => 85226
)
)
[1] => Array
(
[first_name] => Richard
[patient_first_name] => Donna
[trip_date] => 2018-08-24
[request] => Array
[0] => stdClass Object
(
[id] => 55
[client_id] => 10120
[city] => PHX
[state] => AZ
[zip] => 85008
)
[1] => stdClass Object
(
[id] => 59
[client_id] => 11229
[city] => BUCKEYE
[state] => AZ
[zip] => 85326
)
)
[2] => Array
(
[first_name] => Richard
[patient_first_name] => Donna
[trip_date] => 2018-08-24
[request] => Array
[0] => stdClass Object
(
[id] => 69
[client_id] => 13769
[city] => PHOENIX
[state] => AZ
[zip] => 85035
)
[1] => stdClass Object
(
[id] => 175
[client_id] => 16437
[city] => Phx
[state] => Az
[zip] => 85029
)
)
)
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?

Answer 1

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

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;
}
