How can do this?

Answer 1

It would be hard to merge the array's like this. One suggestion is to create the $new_array and key the values by the id of $array_1. Then you can loop over $array_2 and update $new_array using the id from the object in $array_2.

$new_array = [];

foreach ($array_1 as $item) {
    $new_array[$item['id']] = $item;
}

foreach ($array_2 as $item) {
    // Perhaps first make sure that the key exists if array_2 
    // could have a total_time that will not be in array_1
    $new_array[$item->id]['total_time'] = $item->total_time;
}

// In case you must have your keys starting from 0
// you can uncomment the call to array_values.
// $new_array = array_values($new_array);
print_r($new_array);
