 if(!handle=@opendir($dir)){ //Detect whether the directory to be opened exists
 die("There is no such directory");

 $file=$dir .DIRECTORY_SEPARATOR. $file;
 if(is_dir($file)){
 deletedir($file);
 }else{
 if(@unlink($file)){
 echo "file $fileDeletion successful. ";
 }else{
 echo "File$fileDeletion failed!";
