Homephp教程php手册PHP递归删除目录几个代码实例

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');

?>

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
