從循環中的數組獲取值

Question

Im循環播放一些帖子以獲取附加到每個帖子的圖庫。我想收集所有隻包含這些網址的數組中的所有網址。

<?php if ($the_query->have_posts()) { 
    while ($the_query->have_posts()) { 
     $the_query->the_post(); 
     if (get_post_gallery()) : 


        $gallery_images = get_post_gallery_images(); 

        // In each loop $gallery_images will contain a new 
        // array of urls. I would like to add these urls to collect all urls in another array. 

        ?> 
        <?php 
     endif; 
    } 
}?> 

我確定這一定很簡單，但我不能弄明白。幫助讚賞。謝謝！

收集$ gallery_images數組中的所有url不會更容易嗎？

$gallery_images[] = get_post_gallery_images(get_the_ID()); 

另外我相信get_post_gallery_images（）需要post ID或post對象作爲參數。請看這裏：https://codex.wordpress.org/Function_Reference/get_post_gallery_images
