检查数组中是否存在值

Question

I want to check if product exist in wishlist array, so I can make a function to get id of products in wishlist and the result is

Array
    (
    [0] => Array
        (
            [product_id] => 28
        )

    [1] => Array
        (
            [product_id] => 30
        )

    [2] => Array
        (
            [product_id] => 42
        )
    )

my code is

foreach ($products as $product)
 show products in this style else in this style

I want to check if

$product['product_id'] = the product id in $wishids array

You can use in_array with array_column, see example below:

if(in_array($productID, array_column($wishids, 'product_id'))
  echo 'Match found';
else 
  echo 'Match not found';
