php文件缓存数据(3)

    //清除过期缓存文件 

    public function clear(){ 

        $files = scandir($this->cacheDir); 

        foreach ($files as $val){ 

            if (@filemtime($this->cacheDir."/".$val) < time()){ 

                @unlink($this->cacheDir."/".$val); 

            } 

        } 

    } 

    //清除所有缓存文件 

    public function clear_all(){ 

        $files = scandir($this->cacheDir); 

        foreach ($files as $val){ 

            @unlink($this->cacheDir."/".$val); 

        } 

    } 

    private function error($line,$msg){ 

        die("出错文件：".__file__."/n出错行：$line/n错误信息：$msg"); 

    } 

} 

在页面中的调用方法如下:

$cacheFile = new Inc_FileCache(array('cacheTime'=>60,'suffix'=>'.php')); 

//得到电影热播榜 

$where = " where pid=75"; 

$moviehotModel = $this->getM('moviehot'); 

$moviehotCount = $moviehotModel->getCount($where); 

if( !$cacheFile->_isset($where.$moviehotCount.'moviehot') ){ 

    $moviehotResult = $moviehotModel->getList(" WHERE pid=75 ",'0,10',"orderby desc"); 

    if(count($moviehotResult) > 0) { 

        $cacheFile->set($where.$moviehotCount.'moviehot',$moviehotResult); 

    } 

}else{ 

    $moviehotResult = $cacheFile->get($where.$moviehotCount.'moviehot'); 

} 

$this->tpl['moviehotResult'] = $moviehotResult; 

大家如果还有什么好的文件缓存的代码可以拿来共享一下
