问题描述
我在使用scandir()时遇到麻烦.我正在尝试在云子域下页面上的snaps-目录中显示文件.
I am having trouble with scandir(). I am trying to display the files in my snaps-directory on a page under the subdomain in my cloud.
这是我使用的PHP.
$files = scandir('./snaps');
print_r($files);
这是错误.
Warning: scandir(./snaps) [function.scandir]: failed to open dir: No such file or directory in /home/u703778423/public_html/cloud/index.php on line 39
Warning: scandir() [function.scandir]: (errno 2): No such file or directory in /home/u703778423/public_html/cloud/index.php on line 39
我不知道该怎么办
推荐答案
您可能会假设当前工作目录位于编写脚本scandir()的旁边，而在很多情况下不是. >
You probably assume, that the current work directory is next to the script scandir() is written in, which (in many cases) isn't.
scandir(__DIR__ . '/snaps');
