Change response format of REST API - php

Question

I'm working on my REST API responses with PHP.
Here is my backend that generates the responses:
$query = $this->db->query("SELECT some_params from some_table ");
$result = $query->result();
foreach($result as $row){
$obj[] = array(
'title' => $row['title'],
'price' => $row['price'],
);
}
print_r(json_encode($obj));
and with that I have the following response: an array of json objects
[
{
"title":"Marketing",
"price":"0"
},
{
"title":"SAP B1",
"price":"10"
}
]
What I would like to do is return a new object, something like this:
{
"apiVersion": "2.0",
"data": {
{
"title":"Marketing",
"price":"0"
},
{
"title":"SAP B1",
"price":"10"
}
}
}
Does anyone have any idea how I could implement this? thanks!

You can easily have a class or function to do that for you. Some thing like below should help,
// provided you are using php > 7 . otherwise parmas
// can become $data, $apiversion ( without typecasting )
function api_reponse(array $data, string $apiVersion)
{
return json_encode([
'apiVersion' => $apiVersion,
'data' => $data
])
}
You can then use,
$query = $this->db->query("SELECT some_params from some_table ");
$result = $query->result();
foreach($result as $row){
$obj[] = array(
'title' => $row['title'],
'price' => $row['price'],
);
}
print_r( api_response($obj, '2.0') );
