如何从数组中输出名称和价格？

Question

大家好，我想只输出每个产品的名称和产品的价格。 我不想输出ID或其他东西。

 <?php
     $a = array(
    array('id' => '1', 'name' => 'Milch','price' => '12'),
    array('id' => '2', 'name' => 'Reis','price' => '13'),
    array('id' => '3', 'name' => 'Öl','price' => '14'),
    array('id' => '4', 'name' => 'Salz','price' => '15'),
    array('id' => '5', 'name' => 'Zucker','price' => '16'),     
         );
        foreach ($a as $key => $value){
                print_r($a[$key]);
           }
   ?>

foreach ($a as $product) {
   echo $product['name'] . ': $' . $product['price'] . '<br />';
}
