PHP implements method of deleting file directories based on recursion

This article mainly introduces in detail how PHP uses recursion to delete file directories. It has certain reference value. Interested friends can refer to

to delete the directory directly. If it is empty Directories can be deleted. If the directory is not empty, you can only delete the files in the directory first and then delete the directory. I encapsulated a delete function and then called this function directly. You can use it directly if you like it. The encoding is gbk. Please pay attention to the encoding when using it.

<?php
/**

 */
//删除文件，先删除文件内部的文件，再删除文件夹
header("Content-type: text/html; charset=gbk");
function deldir($dir){
 $dh=opendir($dir);
 while($file=readdir($dh)){
 if($file!="." && $file!=".."){//判断是不是本目录和上级目录
 if(!is_dir($dir."/".$file)){
  unlink($dir."/".$file);
 }else{
  //递归
  deldir($dir."/".$file);
 }
 }
 }
 closedir($dh);
 if(rmdir($dir)){
 return true;
 }else{
 return false;
 }
 }
 //删除函数结束
 if(deldir("test")){
 echo &#39;删除文件成功&#39;;
 die();
 }else
 echo &#39;删除文件失败&#39;;
 die();
