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());
}
}
?>
