The DirectoryIterator class provides a simple interface for viewing the contents of filesystem directories.
$mode = "r", bool $useIncludePath = false, ?resource $context = null): SplFileObjectShows us all files and catalogues in directory except "." and "..".
<?php
foreach (new DirectoryIterator('../moodle') as $fileInfo) {
if($fileInfo->isDot()) continue;
echo $fileInfo->getFilename() . "<br>\n";
}
?>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;
}
}
}
?>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
