PHP using recursive implementation to delete file directory _php tips

Delete directory directly, if it is empty directory can be deleted, if not empty directory, this time can only delete the files in the directory, and then delete the directory. I encapsulated a delete function and then called the function directly. Like can be directly used, coding is GBK, use the attention of the code.

<?php
/**
 * Created by Phpstorm.
 * User:administrator
 * DATE:2016/9/10 0010 * time:20:27//
 /delete file, delete file internal file, delete
folder
header (" content-type:text/html; CHARSET=GBK ");
function Deldir ($dir) {
 $dh =opendir ($dir);
 while ($file =readdir ($DH)) {
 if ($file!= "." && $file!= "...") {//Judge whether this directory and superior directory
 if (!is_dir ($dir.) /". $file)) {
  unlink ($dir.) /". $file);
 } else{
  //Recursive
  Deldir ($dir. " /". $file);
 }} Closedir ($DH);
 if (RmDir ($dir)) {return
 true;
 } else{return
 false;
 }
 Delete Function End
 if (Deldir ("test")) {
 echo ' delete file succeeded ';
 Die ();
 } else
 Echo ' delete file failed ';
 Die ();
