(PHP 5 >= 5.3.0, PHP 7, PHP 8)
FilesystemIterator::setFlags — 設定處理旗標
不回傳任何值。
範例 #1 FilesystemIterator::key() 範例
此範例示範了 FilesystemIterator::KEY_AS_PATHNAME 和 FilesystemIterator::KEY_AS_FILENAME 旗標之間的差異。
<?php
$iterator = new FilesystemIterator(dirname(__FILE__), FilesystemIterator::KEY_AS_PATHNAME);
echo "以路徑作為鍵值：\n";
foreach ($iterator as $key => $fileinfo) {
echo $key . "\n";
}
$iterator->setFlags(FilesystemIterator::KEY_AS_FILENAME);
echo "\n以檔名作為鍵值：\n";
foreach ($iterator as $key => $fileinfo) {
echo $key . "\n";
}
?>以上範例在 PHP 8.2 中的輸出類似於
Key as Pathname: /www/examples/. /www/examples/.. /www/examples/apple.jpg /www/examples/banana.jpg /www/examples/example.php Key as Filename: . .. apple.jpg banana.jpg example.php
