Get specific key value pairs from associative array

I`m new to PHP and probably this one is basic question, but...I have an associative array (result of json_decode function). For example it looks like this: 

$cars = array
  (
  array("brand"=>"Volvo", "price" => 10000, "type"=> 1),
  array("brand"=>"Audi", "price" => 20000, "type"=> 2),
  array("brand"=>"Ford", "price" => 30000, "type"=> 3),
  array("brand"=>"Audi", "price" => 31000, "type"=> 3),
  array("brand"=>"Ford", "price" => 32000, "type"=> 2),
  array("brand"=>"Audi", "price" => 33000, "type"=> 2)
  );

I need to loop $cars and get just brand and price as key value pair where brand is Audi because of a need to convert each to an object then.

Thanks!

Pretty simple. Use foreach to iterate through each car. If car brand name is 'Audi' then it will add it the entry it's on to an array.

<?php
$cars = array
  (
  array("brand"=>"Volvo", "price" => 10000, "type"=> 1),
  array("brand"=>"Audi", "price" => 20000, "type"=> 2),
  array("brand"=>"Ford", "price" => 30000, "type"=> 3),
  array("brand"=>"Audi", "price" => 31000, "type"=> 3),
  array("brand"=>"Ford", "price" => 32000, "type"=> 2),
  array("brand"=>"Audi", "price" => 33000, "type"=> 2)
  );

$audis = [];  
foreach ($cars as $car) {
  if ($car['brand'] == 'Audi') {
    $audis[] = ['price' => $car['price'], 'type' => $car['type']];
  }
}

foreach ($audis as $audi) {
  print_r($audi);
}

This returns all Audi's

Array
(
    [price] => 20000
    [type] => 2
)
Array
(
    [price] => 31000
    [type] => 3
)
Array
(
    [price] => 33000
    [type] => 2
)
