范例

示例 #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
