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

If you need two columns from an array where one is SKU (which generally is unique) then you can use array_column with the third parameter.

$new = array_column($arr, "product_id", "product_sku");

This will return a flat array with the SKU as the key and ID as value making the array easy to work with also.

Output:

array(3) {
  [6500722]=>
  string(4) "1138"
  [6501046]=>
  string(4) "1144"
  [6294915]=>
  string(3) "113"
}
