php - 多次元配列の次元を減らす

Question

この製品情報の配列を反復処理するのに問題があり、各アイテムの Google e コマース追跡コードをエコーするという望ましい結果が得られます。次元を 1 減らす方法を教えてください。要するに -

これをどのように回すか：

Array (
    [array] => Array (
        [0] => Array (
            [product_id] => 7
            [prod_count] => 1
            [price] => 19.99
        )
        [1] => Array (
            [product_id] => 6
            [prod_count] => 3
            [price] => 19.99
        )
        [2] => Array (
            [product_id] => 5
            [prod_count] => 2
            [price] => 19.99
        )
        [3] => Array (
            [product_id] => 4
            [prod_count] => 4
            [price] => 14.99
        )
        [4] => Array (
            [product_id] => 3
            [prod_count] => 5
            [price] => 19.99
        )
    )
 )

これに：

 Array (
            [0] => Array (
                [product_id] => 7
                [prod_count] => 1
                [price] => 19.99
            )
            [1] => Array (
                [product_id] => 6
                [prod_count] => 3
                [price] => 19.99
            )
            [2] => Array (
                [product_id] => 5
                [prod_count] => 2
                [price] => 19.99
            )
            [3] => Array (
                [product_id] => 4
                [prod_count] => 4
                [price] => 14.99
            )
            [4] => Array (
                [product_id] => 3
                [prod_count] => 5
                [price] => 19.99
            )
        )
