主要实现了在后台查看日志列表及打包下载功能。

由于用到了PHP压缩功能，特此记录下。

压缩下载类：

Hzip.php

    addFile($filePath, $localPath);                } elseif (is_dir($filePath)) {                    // Add sub-directory.                    $zipFile->addEmptyDir($localPath);                    self::folderToZip($filePath, $zipFile, $exclusiveLength);                }            }        }        closedir($handle);    }    private static function fileToZip($folder, &$zipFile, $exclusiveLength) {        $localPath = substr($folder, $exclusiveLength);        $zipFile->addFile($folder, $localPath);    }    /**     * Zip a folder (include itself).     * Usage:     *   HZip::zipDir('/path/to/sourceDir', '/path/to/out.zip');     *     * @param string $sourcePath Path of directory to be zip.     * @param string $outZipPath Path of output zip file.     */    public static function zipDir($sourcePath, $outZipPath)    {        $pathInfo = pathinfo($sourcePath);        $parentPath = $pathInfo['dirname'];        $dirName = $pathInfo['basename'];        $z = new ZipArchive();        $z->open($outZipPath, ZipArchive::CREATE);        $z->addEmptyDir($dirName);        if(is_dir($sourcePath)){            self::folderToZip($sourcePath, $z, strlen("$parentPath/"));        }else{            self::fileToZip($sourcePath, $z, strlen("$parentPath/"));        }        $z->close();    }    public static function download($file){//        $filename = sys_get_temp_dir() ."/log.zip"; //最终生成的文件名（含路径）        $filename = sys_get_temp_dir() ."/". basename($file) . '.zip'; //最终生成的文件名（含路径）        self::zipDir($file, $filename);//        header("Cache-Control: public");//        header("Content-Description: File Transfer");//        header("Content-type:  application/octet-stream ");//        header("Accept-Ranges:  bytes ");        header('Content-disposition: attachment; filename='.basename($filename)); //文件名        header("Content-Type: application/zip"); //zip格式的        header("Content-Transfer-Encoding: binary"); //告诉浏览器，这是二进制文件        header('Content-Length: '. filesize($filename)); //告诉浏览器，文件大小        ob_clean();        flush();        @readfile($filename);    }    /**     * 转换文件大小     * @param $fileSize     * @return string     */    public static function convertSize($fileSize) {        $size = sprintf("%u", $fileSize);        if($size == 0) {            return("0 Bytes");        }        $sizename = array(" Bytes", " KB", " MB", " GB", " TB", " PB", " EB", " ZB", " YB");        return round($size/pow(1024, ($i = floor(log($size, 1024)))), 2) . $sizename[$i];    }    /**     * 获取文件夹大小     * 不建议使用，太慢     * @param $dir     * @return int     */    public static function getDirSize($dir)    {        //避免计算父级目录        if(stripos($dir, '..')){            return filesize($dir);        }        $sizeResult = 0;        $handle = opendir($dir);        while (false!==($FolderOrFile = readdir($handle)))        {            if($FolderOrFile != "." && $FolderOrFile != "..")            {                if(is_dir("$dir/$FolderOrFile")){                    $sizeResult += self::getDirSize("$dir/$FolderOrFile");                }else{                    $sizeResult += filesize("$dir/$FolderOrFile");                }            }        }        closedir($handle);        return $sizeResult;    }}?>

逻辑部分无非就是打开某个目录，然后列出来：

/**     * 日志管理     */    public function LogsList(){        //默认路径        $default_dir = APP_PATH . "Logs/";        //获取路径        if(isset($_GET['path'])){            $dirpath =   $_GET['path'];        }else{            $dirpath =  $default_dir;        }        //路径安全检查        if(stripos($dirpath, 'Logs') === false){            $dirpath =  $default_dir;        }        //规范化路径        $dirpath = realpath($dirpath);        //操作        $op = empty($_GET['op']) ? 'list' : $_GET['op'];        switch ($op){            case 'list':                $this->LogsListList($dirpath);                break;            case 'download':                \Yjc\Hzip::download($dirpath);                break;        }    }    private function LogsListList($dirpath){        //打开路径        $d  =  dir($dirpath);        $data = array();        $data['path'] = $d -> path;//        $data['log_path'] = getDomain() . "/Logs/http/$date";        while ( false  !== ( $entry  =  $d -> read ())) {//            $entryname = realpath($d -> path .'/'. $entry);            $entryname = $d -> path .'/'. $entry;//            $filesize = \Yjc\Hzip::getDirSize($entryname);            $filesize = filesize($entryname);            $files = array(                'path' => $d->path,                'name' => $entry,                'entry' => $entryname,                'size' => \Yjc\Hzip::convertSize($filesize),//大小                'mtime' => filemtime ($entryname),                'type' => is_dir($entryname) ? 'dir' : 'file',                'can_down' => in_array($entry, array('.', '..')) ? 0 : 1,            );            $filenames[] = $entry;            $data['entrys'][] = $files;        }        //排序        array_multisort($filenames,SORT_ASC,SORT_STRING, $data['entrys']);        $d -> close ();//        dump($data);        $this->assign('data', $data);        $this->display(':http_logs_list');    }

前端把$data展示出来就行啦：

         {$vo.name}                       
                              {$vo.name}                  
                            
                         
{$vo.size}
                         
{$vo.type}
                         
{$vo.mtime|date='Y-m-d H:i:s' , ###}
                         
                      
                                  
         下载
