DirectoryIterator クラス
(PHP 5, PHP 7, PHP 8)
はじめに
DirectoryIterator クラスは、 ファイルシステムのディレクトリを閲覧するためのシンプルなインターフェイスです。
クラス概要
/* メソッド */
/* 継承したメソッド */
public SplFileInfo::openFile(string
}$mode = "r", bool $useIncludePath = false, ?resource $context = null): SplFileObject目次
- DirectoryIterator::__construct — パスから新規ディレクトリイテレータを生成する
- DirectoryIterator::current — 現在の DirectoryIterator アイテムを返す
- DirectoryIterator::getBasename — 現在の DirectoryIterator のアイテムのベース名を取得する
- DirectoryIterator::getExtension — ファイルの拡張子を取得する
- DirectoryIterator::getFilename — 現在の DirectoryIterator アイテムのファイル名を返す
- DirectoryIterator::isDot — 現在の DirectoryIterator アイテムが '.' もしくは '..' であるかどうかを調べる
- DirectoryIterator::key — 現在の DirectoryIterator アイテムのキーを返す
- DirectoryIterator::next — 次の DirectoryIterator アイテムに移動する
- DirectoryIterator::rewind — DirectoryIterator を最初に巻き戻す
- DirectoryIterator::seek — DirectoryIterator のアイテムを移動する
- DirectoryIterator::__toString — ファイル名を文字列として取得する
- DirectoryIterator::valid — 現在の DirectoryIterator の位置が有効なファイルであるかどうかチェックする

Beware of the behavior when using FilesystemIterator::UNIX_PATHS, it's not applied as you might expect.
I guess this flag is added especially for use on windows.
However, the path you construct the RecursiveDirectoryIterator or FilesystemIterator with will not be available as a unix path.
I can't say this is a bug, since most methods are just purely inherited from DirectoryIterator.
In my test, I'd expected a complete unix path. Unfortunately... not quite as expected:
<?php
// say $folder = C:\projects\lang
$flags = FilesystemIterator::KEY_AS_PATHNAME | FilesystemIterator::CURRENT_AS_FILEINFO | FilesystemIterator::SKIP_DOTS | FilesystemIterator::UNIX_PATHS;
$d_iterator = new RecursiveDirectoryIterator($folder, $flags);
echo $d_iterator->getPath();
?>
expected result: /projects/lang (or C:/projects/lang)
actual result: C:\projects\lang

DirectoryIterator is just an lightweight SplFileInfo iterator and its methods operate on whatever item the internal cursor points to. In other words:
<?php
$iterator = new DirectoryIterator('C:\\');
echo $iterator->getPathname();
?>
... will NOT print "C:\" but the path of the first file or subdirectory retrieved, e.g. "C:\$Recycle.Bin".

DirectoryIterator::getBasename() has been also been available since 5.2.2, according to the changelog (not documented yet). It takes a parameter $suffix, and is useful if, for instance, you use a naming convention for your files (e.g. ClassName.php).
The following code uses this to add recursively All*Tests.php in any subdirectory off of tests/, basically, suites of suites.
<?php
// PHPUnit boilerplate code goes here
class AllTests {
public static function main() {
$parameters = array('verbose' => true);
PHPUnit_TextUI_TestRunner::run(self::suite(), $parameters);
}
public static function suite() {
$suite = new PHPUnit_Framework_TestSuite('AllMyTests'); // this must be something different than the class name, per PHPUnit
$it = new AllTestsFilterIterator(
new RecursiveIteratorIterator(
new RecursiveDirectoryIterator(dirname(__FILE__) . '/tests')));
for ($it->rewind(); $it->valid(); $it->next()) {
require_once($it->current());
$className = $it->current()->getBasename('.php');
$suite->addTest($className::suite());
}
return $suite;
}
}
?>
Also, the AllTestsFilterIterator above extends FilterIterator, and contains one method, accept():
<?php
class AllTestsFilterIterator extends FilterIterator {
public function accept() {
if (preg_match('/All.*Tests\.php/', $this->current())) {
return true;
} else {
return false;
}
}
}
?>

Implements Iterator so you can foreach() over the content of the given directory

Deleting all files in a directory except the one which is last modified.
<?php
$directory = dirname(__FILE__)."/demo";
$filenames = array();
$iterator = new DirectoryIterator($directory);
foreach ($iterator as $fileinfo) {
if ($fileinfo->isFile()) {
$filenames[$fileinfo->getMTime()] = $fileinfo->getFilename();
}
}
ksort($filenames);
print_r($filenames);
echo "\n";
$i=0;
if(sizeof($filenames)>1){
foreach ($filenames as $file){
if($i>0){
echo $file."\n";
unlink($directory."/".$file);
}
$i++;
}
}
?>

For some reason, the `isDot()` method doesn't return positive for the `.DS_Store` file generated by Mac OS's Finder. In practice, I've had to write code to explicitly check for this file:
<?php
foreach (new DirectoryIterator('../moodle') as $fileInfo) {
if($fileInfo->isDot() || $fileInfo->getBasename() === '.DS_Store') continue;
echo $fileInfo->getFilename() . "<br>\n";
}
?>
