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());
}
}
?>
以上例程的输出类似于：
Matched 2 item(s) [1] php5ts.dll [2] php_gd2.dll
