删除一个空目录用rmdir() 函数即可搞定。但是要删除一个非空目录,则无法进行快速的删除,必须先将目录中文件删除,但是目录里可能还会有子目录,因此我们需要进

下面给大家提供几个函数参考。

实例一:

复制代码 代码如下:


function deletedir($dir){ 
      if(!handle=@opendir($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$file删除成功。
"; 
                                  }else{ 
                                          echo  "文件$file删除失败!
"; 
                                 } 
                } 
     } 
    if(@rmdir($dir)){ 
           echo "目录$dir删除成功了。
\n"; 
    }else{ 
           echo "目录$dir删除失败!
\n"; 
  } 


//测试程序 
$dir="/var/www/test"; 
deletedir($dir); 
?> 

实例二:Php递归删除目录方法(兼容中文目录和文件)

复制代码 代码如下:


/*
本函数支持中文删除目录,由于我只测试了window下删除,linux未测试,如有问题可留言或者自己稍加修改即可。
如有错误欢迎大家指正,,共同学习
*/
header("Content-type: text/html; charset=gb2312");

function delete_dir($tmp_path){

 
    if(!is_writable($tmp_path) && is_dir($tmp_path)){
        chmod($tmp_path,0777);
    }

    $encode = mb_detect_encoding($tmp_path, array('UTF-8','GB2312','ASCII','GBK'));
    $tmp_path = iconv($encode,'gb2312',$tmp_path);

 
    $handle_object = scandir($tmp_path);

 
    if(count(scandir($tmp_path))==2){

        if(rmdir($tmp_path)){
            echo $tmp_path.'
';
        }else{
            echo $tmp_path.'
';
        }

        return ;

    }

    foreach($handle_object as $val){       

        if($val!='..' && $val!='.' && $val!=''){

            if(filetype($tmp_path.'/'.$val)=='dir'){

                if(count(scandir($tmp_path.'/'.$val))==2){
                    if(rmdir($tmp_path.'/'.$val)){
                        echo $$tmp_path.'/'.$val.'
';
                    }else{
                        echo $$tmp_path.'/'.$val.'
';
                    }
                }else{
                    delete_dir($tmp_path.'/'.$val);
                }          
            }else{
                if(unlink($tmp_path.'/'.$val)){
                    echo $$tmp_path.'/'.$val.'
';
                }else{
                    echo $$tmp_path.'/'.$val.'
';
                }
            }          
        }else{

            continue;
        }

    }

    
    if(rmdir($tmp_path)){
        echo $tmp_path.'
';
    }else{
        echo $tmp_path.'
';
    }

        return ;

    
}

delete_dir('D:/AppServ/www/testing/哈哈');

?>
