Example #1 GlobIterator example

<?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());
