在foreach循环php中创建多个数组

Question

我正在尝试从 foreach 循环创建多个数组，因此每次循环遍历项目时，它都会创建一个包含所有值的数组。然后我希望将这些值插入到主数组中。

所以本质上，我希望产品名称、ID、数量等在一个数组中，然后下一个项目在另一个数组中。然后这些将位于主 $cartinfo 数组中。

目前，当它遍历项目时，会将它们添加到单个数组中。谁能帮帮我？

function cart_items_array() { 

    $cartinfo = array();

    $carts2 = MultiCart\get_carts();

    foreach ( $carts2 as $cart2_id => $cart2 ) {
         // get array of items contained in a cart ...
        $items2 = MultiCart\get_cart( $cart_id2 );

        foreach ( $items2 as $item2_id => $item2 ) {

                $product_name = get_post($item2['product_id'])->post_title; 
                $familyterms = wp_get_post_terms( $item2['product_id'], 'pa_product-family'); 
                $cat_terms = wp_get_post_terms( $item2['product_id'], 'pa_product-category'); 
                $product_sku = get_post_meta( $item2['product_id'], '_sku', true );

                $cartinfo[] = $product_sku; 
                foreach ($cat_terms as $cat_term) { $cartinfo[] = $cat_term->name; };
                foreach ($familyterms as $family) { $cartinfo[] = $family->name; }; 
                $cartinfo[] = $product_name;
                $cartinfo[] = $item2['quantity'];
                $cartinfo[] = $cart2['name'];

        }
    } 

    return $cartinfo;
}

如果我错了，请纠正我。

你想做这样的事情吗：

function cart_items_array() { 

$cartinfo = array();

$carts2 = MultiCart\get_carts();

// All the products
$allTheCarts = array();

foreach ( $carts2 as $cart2_id => $cart2 ) {
     // get array of items contained in a cart ...
    $items2 = MultiCart\get_cart( $cart_id2 );

    foreach ( $items2 as $item2_id => $item2 ) {
            $compProduct = array();
            $product_name = get_post($item2['product_id'])->post_title; 
            $familyterms = wp_get_post_terms( $item2['product_id'], 'pa_product-family'); 
            $cat_terms = wp_get_post_terms( $item2['product_id'], 'pa_product-category'); 
            $product_sku = get_post_meta( $item2['product_id'], '_sku', true );

            $cartinfo[] = $product_sku; 
            foreach ($cat_terms as $cat_term) { $cartinfo[] = $cat_term->name; };
            foreach ($familyterms as $family) { $cartinfo[] = $family->name; }; 
            $cartinfo[] = $product_name;
            $cartinfo[] = $item2['quantity'];
            $cartinfo[] = $cart2['name'];

            // Store the complete product info
            $allTheCarts[] = $cartinfo;
    }
} 

return $allTheCarts;
}
