The documentation for DirectoryIterator is sparse. I found this nice overview:

/using-directoryiterator-to-list-files-in-php



(The above is one line, but I'm not allowed to post it like that)

In response to the comment below from udvig. The Example ist wrong, here is the right one:



<?php

$dir = new DirectoryIterator("/tmp");

foreach ($dir as $file) {

   if ($file->isDot()) {

       continue;

   }

   echo $file->getFilename() . "\n";

}

?>

In response to the comment below, you don't have to simulate a foreach(), DirectoryIterator obviously inherits SPL's Iterator interface, therefore:



<?php

$dir = new DirectoryIterator("/tmp");

foreach ($dir as $file) {

    if ($dir->isDot()) {

        continue;

    }

    echo $file . "\n";

}

?>

We can now replace the old fashioned way of listing the content from a directory!



the old way:

<?php

if ($handle = opendir('/home/fernando/temp')) {

    while (false !== ($file = readdir($handle))) {

        if ($file != "." && $file != "..") {

            print "$file <br />";

        }

    }

    closedir($handle);

}

?> 



the new way:

<?php

$dir = new DirectoryIterator('/home/fernando/temp');

while($dir->valid()) {

    if(!$dir->isDot()) {

        print $dir->current()."<br />";

    }

    $dir->next();

}

?>

I wrote a function for finding all files in the current and in subdirectories.



The Code:

<?php

function getFiles(&$rdi,$depth=0) {



    if (!is_object($rdi))

        return;

        

    for ($rdi->rewind();$rdi->valid();$rdi->next()) {

        

        if ($rdi->isDot())

            continue;

        

        if ($rdi->isDir() || $rdi->isFile()) {

            

            for ($i = 0; $i<=$depth;++$i)

                echo '&nbsp;&nbsp;&nbsp;';

                

            echo $rdi->current().'<br />';

            

            if ($rdi->hasChildren())

                getFiles($rdi->getChildren(),1+$depth);

        }

    }

}



getFiles(new RecursiveDirectoryIterator('.'));

?>
