Create an array of object PHP - php

Question

I am trying to create this structure on PHP
and I don't know how to I create an array of object on PHP. It always get the last data from the object.
This is my current code:
array(
"description": getDescription($id),
"deposit": getPrices($id);
)
function getPrices($id) {
$test = Prices::where('price_id',$id)->where('promo',0)->get();
$price = [];
$data = [];
foreach($test as $t) {
$data["item_id"] = $t->id;
$data["price"] = $t->list;
$data["type"] = $t->type;
$price = $data;
}
return $price;
}

Answer 1

Fixing the actual issue with not receiving all records from the getPrices function:
array(
"description": getDescription($id),
"deposit": getPrices($id);
)
function getPrices($id) {
$test = Prices::where('price_id',$id)->where('promo',0)->get();
$price = [];
foreach($test as $t) {
$price[] = ["item_id" => $t->id, "price" => $t->list, "type": $t->type];
}
return $price;
}
You're missing the square brackets after $price (Correct: $price[]) variable which tells PHP to append to array rather than actually replace it.
The other option is to use array_push, which is more explicit but does the same; Read more here.
Fixing the issue of serialisation:
You can use json_encode to serialise the array into JSON (JavaScript Object Notation).

Answer 2

$dataArray=array();
foreach($test as $t) {
$dataArray[] = array('item'=> $t->id,'item'=> $t->price,'type'=> $t->type);
}
$finalArray= array('deposit'=>$dataArray);
convert final array to json using json_encode

Answer 3

$structure = new stdClass();
$structure->description = 'tobedefined'; // Define the description here
$structure->deposit = getPrices($id);
function getPrices($id) {
$deposits = array();
// Change this to contain the real data
// $test = Prices::where('price_id',$id)->where('promo',0)->get();
$test = array(
array(
'item_id' => 100,
'price' => '1, 2, 3, 4, 5',
'type' => 'child'
),
array(
'item_id' => 101,
'price' => '2, 4, 6, 8, 10',
'type' => 'child'
),
array(
'item_id' => 102,
'price' => '2, 4, 6, 8, 10',
'type' => 'child'
)
);
foreach ($test as $t) {
$deposit = new stdClass();
$deposit->item_id = $t['item_id'];
$deposit->price = $t['price'];
$deposit->type = $t['type'];
$deposits[] = $deposit;
}
return $deposits;
}
echo 'PHP Structure';
echo '<pre>';
print_r($structure);
echo '</pre>';
echo 'JSON string';
echo '<pre>';
print_r(json_encode($structure, JSON_PRETTY_PRINT));
echo '</pre>';
Output will be:
PHP Structure
stdClass Object
(
[description] => tobedefined
[deposit] => Array
(
[0] => stdClass Object
(
[item_id] => 100
[price] => 1, 2, 3, 4, 5
[type] => child
)
[1] => stdClass Object
(
[item_id] => 101
[price] => 2, 4, 6, 8, 10
[type] => child
)
[2] => stdClass Object
(
[item_id] => 102
[price] => 2, 4, 6, 8, 10
[type] => child
)
)
)
JSON string
{
"description": "tobedefined",
"deposit": [
{
"item_id": 100,
"price": "1, 2, 3, 4, 5",
"type": "child"
},
{
"item_id": 101,
"price": "2, 4, 6, 8, 10",
"type": "child"
},
{
"item_id": 102,
"price": "2, 4, 6, 8, 10",
"type": "child"
}
]
