How to get all all key values of an array in laravel? - json

Question

I am not getting all the key values of and array using foreach, its giving only first key value.
$order_id = DB::table('order')->where('delivery_boy_id', $delivery_boy_id)->where('is_accept', 1)->whereRaw('delivery_completed_at < time_of_assignment')->get();
When i run this code i get two key value
array:2 [0 => {#325
+"id": 37
+"order_id": 8261
+"delivery_boy_id": 8}1 => {#326
+"id": 38
+"order_id": 8261
+"delivery_boy_id": 8]
After using this json response i am getting the response of only one key value
foreach($order_id as $value){ $values = $value) };
$this->response['items'] = $order_id;
return json_encode($this->response);

Answer 1

check this
$order_id = DB::table('order')->where('delivery_boy_id', $delivery_boy_id)->where('is_accept', 1)->whereRaw('delivery_completed_at < time_of_assignment')->get();
// return $order_id;(returns json array)
$data = [];
foreach($order_id as $order)
{
var_dump($order);
//in first loop first array will come
//second loop second array
$data[]=[
'id' => $order['id'],
'..' => '..'
];
}
return $data;
}

Dd means dump and die so it stops execution. If you dd in a for each loop, you will only get the current value in the loop (I.e the first one) because it will halt execution and you will never reach the second loop through. Use var_dump to allow execution to continue and dump variables.
If you simply want to return the Json to the user, you can just return the result of your query as laravel handles serialisation for you. You don't need to loop over the result. See the docs:
https://laravel.com/docs/5.1/eloquent-serialization
You are overwriting $values in your loop. So every time it passes through the for each loop, it overwrites $values with the current $value so it will only ever contain 1 object. You don't need to do the serialisation manually, use the laravel helper methods
Also in your code snippet you are looping over $order, but the result of your query is assigned to $order_id? I'm assuming that's due to abbreviating your code
