原标题:How to efficiently use DirectoryIterator?

我需要从含有文件负荷的目录中删除一些档案。 在我的发言中,这项职能多次被称作。

function getFilteredFiles($criteria) {
    static $files =   ;           
    if ($files ==   ) {
        $files = new DirectoryIterator($path);
    }
    else {
        $files->rewind();
    }

    foreach($files as $file) {
         if (! $file->isDot()) {
             if (!$file->isDir()) {
                  //using $criteria
                  ...
              }
         }
    }
    ...
 }

是否将名录安装在静态变数中,让网址一到档案系统才能查阅档案? (=在构造导师期间,实验室只进入档案系统吗?)

最佳回答

我审视了源代码,并像他们一样试图从你收复机时从目录条目中删除。 我没有把 da树 into入“The php”的溪流。

I guess you could quickly test by using strace.

问题回答

Is putting the DirectoryIterator in a static variable the way to go to let php only go to the filesystem once to get the files? (= does php only go to the filesystem during the __construct of the DirectoryIterator?)

Yes.

但是,为什么你在控制器中创立了一个数据模型的新例子,而不是分类?
