我的功能不起作用:/

服务器中的图像，在以下文件夹中:/public_html/gallery/images

images in server, in folder: /public_html/gallery/images

<?php foreach(glob('gallery/images/*', GLOB_NOSORT) as $image) { echo "Filename: " . $image . "<br />"; } ?>

error i get is : Warning: Invalid argument supplied for foreach() in /home/a9773555/public_html/gallery/index.php on line 2

推荐答案

问题似乎是您已将php文件放在gallery文件夹中.

The problem looks you have put your php file in gallery folder...

/home/a9773555/public_html/gallery/index.php

/home/a9773555/public_html/gallery/index.php on line 2

如果是这种情况(如果您将index.php放在图库中)，请尝试以下操作:

if that is the case (if you put index.php in gallery) then try the following:

<?php foreach(glob('images/*', GLOB_NOSORT) as $image) { echo "Filename: " . $image . "<br />"; } ?>

或执行以下操作，

将index.php放在/home文件夹中.然后...

Put your index.php in your /home folder. then...

<?php foreach(glob('a9773555/public_html/gallery/images/*', GLOB_NOSORT) as $image) { echo "Filename: " . $image . "<br />"; } ?>

尝试一下.让我知道...

Give it a try. and let me know...
