RecursiveDirectoryIterator构造函数返回空对象

Question

I have a problem with the following line:

$iterator = new RecursiveDirectoryIterator($directory);

This code returns an empty object even though the $directory folder contains at least one file. I also double checked the value of $directory and it's the right path

What could be the problem?

Answer 1

Try to use a foreach, because print_f will output empty object even if the object is not empty. You can check this out like that:

foreach ($iterator as $name => $file) {
    echo $file->getRealPath().'<br>';
}

Answer 2

Try this,

$iterator = new RecursiveIteratorIterator(
     new RecursiveDirectoryIterator($path),
    RecursiveIteratorIterator::SELF_FIRST
);

It should get you a file list or throw an exception.
