Shows 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".

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::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;

        }

    }

}

?>

Deleting all files in a directory except the one which is last modified.
<?php

    $filenames = array();
    $iterator = new DirectoryIterator($directory);
    foreach ($iterator as $fileinfo) {
        if ($fileinfo->isFile()) {

        }
    }
    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";
}

?>
