What potential issues could arise when using PHP to recursively move and delete folders on a Windows system?

One potential issue that could arise when using PHP to recursively move and delete folders on a Windows system is the permissions error. This can occur if the PHP script does not have the necessary permissions to access or modify certain folders. To solve this issue, you can run the PHP script with elevated permissions or adjust the folder permissions to allow the PHP script to make changes.

// Set folder permissions recursively
function setFolderPermissions($dir) {
    $iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($dir), RecursiveIteratorIterator::SELF_FIRST);
    
    foreach ($iterator as $item) {
        chmod($item, 0777);
    }
}

// Example usage
setFolderPermissions('C:/path/to/folder');
