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

GlobIterator doesn’t have a way to support GLOB_BRACE! <?php $iterator = new GlobIterator(getcwd. '/*.{php,txt}'); // generate an empty array ?>
