PHP Foreach 返回分离的（单独的）数组

Question

在 foreach 循环中创建的数组是单独的，如下面的结果。我需要它们位于父数组中。

Array

Bellow 是创建上述结果的函数。 $tradesInfo 数组是在嵌套的 foreach 循环之外声明的，但它并没有解决问题！此函数是与 Woocommerce 和 Dokan 一起使用的 Wordpress 脚本的一部分。

if($pageposts)
{
    $tradesInfo = Array();

    foreach($pageposts as $prd)
    {
        if (!is_object($prd)) {
            $query = $wpdb->get_results("SELECT * FROM wp_geo_location WHERE productid=" . $prd . "");
        } else {
            $query = $wpdb->get_results("SELECT * FROM wp_geo_location WHERE productid=" . $prd->post_id . "");
        }

        $array = json_decode(json_encode($query), true);

        foreach($array as $plots)
        {
            $product = wc_get_product($plots["productid"]);

            $author = get_user_by('id', $product->post->post_author);

            // Add cart button or reservation link
            $slug = basename(get_permalink());

            if (function_exists('dokan_get_store_url')) {
                $sellerurl = dokan_get_store_url($author->ID);
            } else {
                $sellerurl = '';
            }

            // Get parent cat ID by product ID
            $prod_terms = get_the_terms($plots["productid"], 'product_cat');

            foreach ($prod_terms as $prod_term) {
                // gets product cat id
                $product_cat_id = $prod_term->term_id;

                // gets an array of all parent category levels
                    $product_parent_categories_all_hierachy = get_ancestors($product_cat_id, 'product_cat');

                // This cuts the array and extracts the last set in the array
                $last_parent_cat = array_slice($product_parent_categories_all_hierachy, -1, 1, true);

                foreach ($last_parent_cat as $last_parent_cat_value) {
                    // $last_parent_cat_value is the id of the most top level category, can be use whichever one like
                    $catID = $last_parent_cat_value;
                }
            }

            $tmp = '<a href="' . get_permalink($product->get_id()) . '" class="button product_type_simple add_to_cart_button" target="_self" ><span>' . __("GO TO SHOP", "pinnergeolocation") . '</span></a>';

            // PRODUCT INFO IN GOOGLE MAP
            if($product != "")
            {
                if ($slug == "medicaments") {
                    $result_slug = printf('<br><a href="%s" title=" ' .__("More Details", "pinnergeolocation") . ' "><span color="#fa6a6a"><b>%s</b></span></a>', esc_url(get_permalink($product->get_id())), __("More Info", "pinnergeolocation"));
                } else {
                    $result_slug = str_replace(array("\n", "\r"), '', $tmp);
                }

                $tradesInfo[] = array(
                    "url" => esc_url(get_permalink($plots["productid"])),
                    "img" => $product->get_image(),
                    "name" => mb_strtoupper(get_the_title($plots["productid"]), "UTF-8"),
                    "desc" => preg_replace('/\s+/', ' ', get_the_excerpt( $product->post )),
                    "seller_url" => $sellerurl,
                    "author_name" => $author->display_name,
                    "slug" => $result_slug,
                    "geoinfo" => array($plots["latitude"], $plots["longitude"])
                );

                $tradesJSON = json_encode($tradesInfo);

                echo $tradesJSON;
            }
        }
    }
}

假设这是你的代码：

foreach($var as $arr){
    $myarray=....; // here you get your array
    print_r($myarray);
}

改变它，将每个数组插入另一个数组：

$wrapArray=array();
foreach($var as $arr){
    $myarray=....; // here you get your array
    $wrapArray[]=$myarray;

}
print_r($wrapArray);
