PHP Delete Files & Folders: Complete Guide

You can use the rmdir() function in PHP to delete empty folders, and use the unlink() function to delete files. Here is an example code:

<?php
$dir = 'path/to/folder';

// 删除文件夹及文件
function deleteFolder($dir) {
    if (is_dir($dir)) {
        $objs = scandir($dir);
        foreach ($objs as $obj) {
            if ($obj != "." && $obj != "..") {
                if (is_dir($dir . "/" . $obj)) {
                    deleteFolder($dir . "/" . $obj);
                } else {
                    unlink($dir . "/" . $obj);
                }
            }
        }
        rmdir($dir);
    }
}

// 调用函数删除文件夹及文件
deleteFolder($dir);
?>

Please be aware that this code will delete all files and subfolders in the specified folder. Make sure to backup important files before using it to prevent accidental data loss.
