php - Get specific key value pairs from associative array -


i`m new php , 1 basic question, but...i have associative array (result of json_decode function). example looks 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 loop $cars , brand , price key value pair brand audi because of need convert each object then.

thanks!

pretty simple. use foreach iterate through each car. if car brand name 'audi' add entry it's on 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 $car) {   if ($car['brand'] == 'audi') {     $audis[] = ['price' => $car['price'], 'type' => $car['type']];   } }  foreach ($audis $audi) {   print_r($audi); }

this returns audi's

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

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...
