Question

I’ve built a system whereby users can start a project and upload files to this project. When they create the project, I create a directory specifically for that project and all uploads fill this directory. However, I have implemented a system that allows the user to remove this project if they wish, deleting all the files within the directory and then the directory itself.

Locally (on MAMP), this worked a charm; on a live server however, it doesn’t. For the directory removal I used a stock piece of code from a tutorial website (posted below) and as I said, works fine on a local webserver.

$name = $_POST['projectName'];
rrmdir("../../project/$name");

    function rrmdir($dir) { 
    if (is_dir($dir)) { 
        $objects = scandir($dir); 
        foreach ($objects as $object) { 
            if ($object != "." && $object != "..") {
                if (filetype($dir."/".$object) == "dir") rrmdir($dir."/".$object); else unlink($dir."/".$object); 
            } 
        } 
        reset($objects); 
        rmdir($dir);
        echo "Directory Removed";
    }

Try this one instead:

$iterator = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator('/path/to/project/directory'),
    RecursiveIteratorIterator::CHILD_FIRST);

foreach($iterator as $fileObject) {
    if($fileObject->isFile()) {
        echo 'Removing File: ', $fileObject->getRealpath(), PHP_EOL;
        // unlink($fileObject->getRealpath());
    } elseif($fileObject->isDir()) {
        echo 'Removing Dir: ', $fileObject->getRealpath(), PHP_EOL;
        // rmdir($fileObject->getRealpath());
    }
}

Uncomment the rmdir and unlink lines to actually perform the removals.
