监听文件夹和文件(更改)

问题描述

可以直接在PHP或Node上侦听文件夹和文件的更改(按事件)，或者我需要使用自己的方法来做到这一点?

It's possible to listen folders and files changes (by events) on PHP or Node directly, or I need make my own method to do it?

示例:我需要收听文件夹/user.如果我将一些文件添加到该目录中，则PHP或Node会接收到该信息并例如运行PathEvent::fileAdded("/user/user.profile").如果我重命名文件夹，它将运行PathEvent::pathRenamed("/user/save1", "/user/save2").

Example: I need to listen the folder /user. If I add some file into this directory the PHP or Node receives the information and run PathEvent::fileAdded("/user/user.profile") for instance. If I rename a folder it run PathEvent::pathRenamed("/user/save1", "/user/save2").

我知道PHP没有像Node这样的事件系统.但是对于PHP，例如，我可以运行一个方法(目前尚不知道)，该方法具有自上次检查以来发生的更改.

I know that PHP don't have an event system like Node. But for PHP I can, for instance, run a method (that I don't know currently) that have the changes ocurred since last time checked.

好吧...我只需要一种开始搜索的方式，我不知道搜索的确切含义是什么.如果您可以举一个例子，那就太好了！ :P

Well... I need only a way to start searching, I don't know exactly what is the term of this search. If you can show me an example, it'll be great too! :P

推荐答案

Node.js提供了此功能.您可以在此处阅读.

Node.js provides this functionality. You can read bout this here.

简单的例子:

var fs = require('fs');

fs.watch('somedir', function (event, filename) {
    console.log(event);
    console.log(filename);
});
