Question

Here is function that I'm using for recursively deleting folders and files

function rmdir_recursively($dir) {
    if (!is_dir($dir) || is_link($dir)) return unlink($dir); 
        foreach (scandir($dir) as $file) { 
            if ($file == '.' || $file == '..') continue; 
            if (!rmdir_recursively($dir . DIRECTORY_SEPARATOR . $file)) { 
                chmod($dir . DIRECTORY_SEPARATOR . $file, 0777); 
                if (!rmdir_recursively($dir . DIRECTORY_SEPARATOR . $file)) return false; 
            }; 
        } 
        return rmdir($dir); 
}

The problem is, when I send some folder inside root, it deletes this folder. But when I send root folder itself like that

rmdir_recursively("./");

It returns bunch of errors like below

PHP Warning:  unlink(.//wp/wp-admin/network) [<a href='function.unlink'>function.unlink</a>]: No such file or directory in /home/vefa/public_html/deploy.php on line 52

What am I missing?

Was it helpful?

Solution

You say you're sending it rmdir_recursively("./");?

But look at the code, you are later calling rmdir_recursively($dir . DIRECTORY_SEPARATOR . $file).

This means that you'll be trying to eliminate files in ".//".

Which is why your error message contains unlink(.//wp/wp-admin/user)

Use rmdir_recursively("."); instead.
