PHP多维数组foreach不起作用

Question

我有一个阵列.我希望将每张照片都放在一个独特的项目中.例如:在我的Facebook上我发布图像如果我发布单张图片然后photosArray有一个项目,但如果我在帖子中发布多个图像,那么photosArray有多个项目.

现在我想打印所有的照片怎么样.

我正在尝试这个代码,但它不起作用

foreach($specified_post_photo_array AS $item)
{


    foreach($item['photosArray'] AS $pitem)
    {
        $photo=$pitem['url'];



    }

}

但它显示没有结果

Answer 1

您应该将代码更改为:

foreach($specified_post_photo_array[0] AS $item)
{


    foreach($item['photosArray'] AS $pitem)
    {
        $photo=$pitem['url'];



    }

}
