PHP - 系统找不到指定的路径。 （但它从另一个文件中找到它）

Question

My main app is at:

'.app/index.php'

What I do from there is parse a directory

foreach (new DirectoryIterator('./app/uploads/images/') as $fileInfo) {
    if($fileInfo->isDot()) continue;
    $images[] = $fileInfo->getFilename();
}

And it works ok.

But, when I do the exact same thing from

'./app/models/tricky.php'

I get the error from the title.

Any clue what I'm doing wrong?

I also tried modifying path to '../app/uploads/images/' but have no clue what else to do.

Thanks.

The difference and simple problem is:

You're two scripts are not in the same directory. If you use the './directory' notation, the '.' means starting at your current directory which is one time 'app' and the other time 'app/models/'.

Solve the problem by changing the path string in 'app/models/tricky.php' to '../uploads/images/'. The double dot '..' is important, it stands for the parent directory (go one directory up).
