PHP通过从另一个数组传递值而不使用foreach从数组中获取值

Question

I've two arrays $products and $id_n_qty $id_n_qty array contains Product id and its quantity where $products array contains all products with their IDs and name.

$products = array(1=>"Shampoo",2=>"Towel");
$id_n_qty = array(1=>3);

My question is how can i get the Product name when i have the $id_n_qty with me without using php foreach?

Thanks

Try with array_keys like

$key_val = array_keys($id_n_qty);
echo $products[$key_val[0]];

Considering that you have only single array in the $id_n_qty.
