如何通过在浏览器中运行页面来删除文件和文件夹？

Question

My function below works, but in Linux, some files and folders are not removed, I believe it is, the server does not allow to be running in browser.

If I run the function in shh or give permission for 777 shh or ftp, files and folders are deleted normally.

But the server blocked permission change for browser.

I guess I need to run my pagina.php the shell, but how to do this in a pagina.php running on the browser?

My function:

<?php
    function deleteItem($item) {
        if (file_exists($item)) {
            if (is_dir($item)) {
                $folders = scandir($item);
                foreach ($folders as $folder) {
                    if ($folder != '.' && $folder != '..') {
                        $file = $item . "/" . $folder;
                        if (filetype($file) == "dir") {
                            deleteItem($file);      
                        } else {
                            unlink($file);
                        }   
                    }               
                }
                reset($folders);
                rmdir($item);               
            } else {            
                unlink($item);          
            }                        
        }
    }
?>

The solution was to alert the User to change the permissions of that was not possible to remove, and rotate and refresh the page.
