PHP - get multiple columns from array

Question

I have this array:

0 => array:3 [
    \"product_id\" => \"1138\"
    \"product_image\" => \"/resources/medias/shop/products/shop-6500720--1.png\"
           


        

Answer 1

I refactored the elegant approach from @Chayan into a function so it can be used like array_column(). Keys to be filtered can now be presented as a simple array.

Btw this is most likely also the fastest approach, since it uses build-in functions for most of the heavy lifting.

 "1138",
        "product_image" => "/resources/medias/shop/products/shop-6500720--1.png",
        "product_sku"   => "6500722"
    ],
    [
        "product_id"    => "1144",
        "product_image" => "/resources/medias/shop/products/shop-6501041--1.png",
        "product_sku"   => "6501046"
    ],
    [
        "product_id"    => "113",
        "product_image" => "/resources/medias/shop/products/shop-6294909--1.png",
        "product_sku"   => "6294915"
    ]
);

$keysSelect = array("product_id" , "product_sku");
$filteredArray = array_colums($arr, $keysSelect);

var_dump($filteredArray);
