如何使用glob从目录中获取图像 - 以前的帖子不起作用

问题描述：

I'm new to php and I'm trying to get a directory listing of images.
I saw this post: How to get random image from directory using PHP

I am trying to do nearly the same thing- choosing a random image and drawing it to the page via an tag.

For some reason, the specification to the directory that I am using doesn't work, but I'm not sure why. I've tried the following:

$localdir = $_SERVER['DOCUMENT_ROOT'] . '/wp_content/themes/overlandconsulting_2010/images/headers/*.{jpg,gif,png}';
$images = glob($localdir, GLOB_BRACE);

$httpdir = $_SERVER['SERVER_NAME'] . '/wp_content/themes/overlandconsulting_2010/images/headers/*.{jpg,gif,png}';
$images = glob($httpdir, GLOB_BRACE);

Neither seems to find any images. :s FWIW, I can navigate to the directory explicitly and see the contents, like this

It seems like the server won't let me access the images, but honestly I have no idea.

Thanks for any help! jml

我试图做几乎相同的事情 - 选择随机图像并通过标签将其绘制到页面上。 p>

For 某些原因，我使用的目录的规范不起作用，但我不知道为什么。我尝试了以下内容： p>

  $ localdir = $ _SERVER ['DOCUMENT_ROOT']。  '/wp_content/themes/overlandconsulting_2010/images/headers/*.{jpg,gif,png}';
$images = glob（$ localdir，GLOB_BRACE）; 
 
 $ httpdir = $ _SERVER ['SERVER_NAME']  。  '/wp_content/themes/overlandconsulting_2010/images/headers/*.{jpg,gif,png}';
$images = glob（$ httpdir，GLOB_BRACE）; 
  code>  pre> 
 
  似乎都没有找到任何图像。  ：s 
FWIW，我可以显式导航到该目录并查看内容，例如

似乎服务器不允许我访问图像，但老实说我不知道。 p> 
  
 
感谢您的帮助！

答

the url in the code has wp_content with an underscore while the link to the directory has wp-content with a hyphen.
