Example #1 RecursiveDirectoryIterator example

<?php

$directory = '/tmp';

$it = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory));

$it->rewind();
while($it->valid()) {

    if (!$it->isDot()) {
        echo 'SubPathName: ' . $it->getSubPathName() . "\n";
        echo 'SubPath:     ' . $it->getSubPath() . "\n";
        echo 'Key:         ' . $it->key() . "\n\n";
    }

    $it->next();
}

?>

The above example will output something similar to:

SubPathName: fruit/apple.xml
SubPath:     fruit
Key:         /tmp/fruit/apple.xml

SubPathName: stuff.xml
SubPath:     
Key:         /tmp/stuff.xml

SubPathName: veggies/carrot.xml
SubPath:     veggies
Key:         /tmp/veggies/carrot.xml
