Example#1GlobIteratorexample

<?php
$iterator = new GlobIterator('*.dll', FilesystemIterator::KEY_AS_FILENAME);
if (!$iterator->count()) {
    echo 'No matches';
} else {
    $n = 0;
    printf("Matched %d item(s)\r\n", $iterator->count());
    foreach ($iterator as $item) {
        printf("[%d] %s\r\n", ++$n, $iterator->key());
