php 图片清理工具web版

该工具可以直接清理大于1mb的图片，扫描出来然后进行删除
访问该文件需要输入一个密码admin123 密码在文件里面可以自行修改
可以清理uploads里面所以子目录里面大于1m的图片
以下是代码
<?php
// 安全措施：限制直接访问
if (php_sapi_name() === 'cli') {
    die("该脚本只能通过Web界面访问");
}

// 配置设置
// $targetDir = __DIR__ . '/uploads';
$targetDir = __DIR__ ;
$maxSize = 1048576; // 1MB
$imageExtensions = ['jpg', 'jpeg', 'png', 'gif', 'webp', 'bmp'];
