文件到数组-Glob vs RecursiveIteratorIterator

Question

I'm adding a list of files to an array by doing:

$files = glob($path."*.*");

I can output the array with print_r(array_values($array)); .

Now I'm trying to do the same with RecursiveIteratorIterator :

$files = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($path)
);

That does not work like expected when I try to output the array?

print_r(array_values($files));

How can I get the same result?

Iterators are not the same as arrays. To use an iterator, you have to iterate over it with foreach .

<?php
$path = "test.dir";
$files = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($path)
);
$file_array = array();
foreach ($files as $f) {
    $file_array[] = $f;
}
print_r($file_array);

Output:

Array
