PHP 文件操作之打包压缩本地目录为tar.gz包

代码打包目录为tar.gz压缩包（除了下载7-Zip软件之外的另一种方式），主要使用php自有拓展PharData，本来是感兴趣测试一下，还有一点问题是文件名太长报错，应该是addFile函数不支持,最后随便封装了一下

    $path   = 'C:/Users/Administrator/Desktop/须打包压缩目录';
    $obj    = new TarGz($path,'default',false,false);
    $obj->createTarGz();

随便封装成类，不是很严谨

class TarGz{
        protected $files    = NULL;

        protected $isDown   = NULL;
        protected $isDel    = NULL;
        protected $model    = NULL;
        protected $tar      = NULL;
        protected $tarGz    = NULL;
        protected $dirPath  = NULL;
        protected $path   = NULL;

        function __construct($path,$model,$isDown,$isDel)
        {
            $this->path     = $path;
            $this->dirPath  = dirname($path).'/';

            $this->isDown   = $isDown;
            $this->isDel    = $isDel;
            $this->model    = $model=='tree' ? 1:0;
            $this->tar      = str_replace($this->dirPath,'',$this->path).'.tar';
            $this->tarGz  = $this->tar.'.gz';
        }

        protected function searchDir($path,&$files){
            if(is_dir($path)){
                $opendir = opendir($path);
                while ($file = readdir($opendir)){
                    if($file != '.' && $file != '..') $this->searchDir($path.'/'.$file, $files);
                }
                closedir($opendir);
            }
            if(!is_dir($path)) {
                if($this->model){

                }else{
                    $files[] = str_replace($this->dirPath,'',$path);
                }
            }
        }

        public function createTarGz()
        {
            $this->searchDir($this->path,$this->files);
            $phar   = new PharData($this->tar);
            $dirs   = array();
            foreach ($this->files as $f) {
                $local = $this->dirPath.$f;
                $dir   = dirname($local);
                $dirs[$dir] = true;
                if(!isset($dirs[$dir])) $phar->addEmptyDir($dir);
                $phar->addFile($local, $f);
            }
            $phar->compress(Phar::GZ);
            if($this->isDown) $this->DownTarGz($this->tarGz);
            if($this->isDel) $this->DelTarGz($this->tarPath, $this->tarGz);

        }
        public function DownTarGz($tarGz)
        {
            header("Content-Type: application/x-gzip");
            //二进制文件没有特定或已知的subtype，即使用 application/octet-stream，这是应用程序文件的默认值，一般很少直接使用
            //header("Content-type:application/octet-stream");
            header("Accept-Ranges:bytes");
            header("Accept-Length: " . filesize($tarGz));
            Header("Content-Disposition:attachment; filename=records.tar.gz");
            //读取一个文件，并写入到输出缓冲
            //@readfile($tarGz);

        }
        public function DelTarGz($tar,$tarGz)
        {
            //临时tar和tar.gz压缩文件，删除重点=权限
            @unlink($tar);
            @unlink($tarGz);
