Solution:
Usearray_chunk() to group the array into chunks of 5 elements. Then you can convert each chunk into an associative array.
$chunks = array_chunk($data, 5);
$result = array_map(function($chunk) {
$arr = [];
foreach ($chunk as $entry) {
foreach ($entry as $key => $val) {
$arr[$key] = $val;
}
}
return $arr;
}, $chunks);
