PHP框架中库和助手之间的区别 [英] difference between libraries and helpers in php frameworks

问题描述

如果我有字符串函数，我使用了很多，我应该把它们放在助手类还是库类中？

函数如下：truncate string if longer超过30个字符，返回一个随机字符串，使所有小写字母等。这些是我可能不需要创建对象的函数。

我应该把它们放在一个库类还是一个辅助类中？

解决方案

帮手是帮助已经存在的东西的类，例如可以有一个帮助器：

数组

字符串

url

等

库可以是任何解决方案;它可能是你第一次创建，也没有其他人创建。

因为你正在处理一个字符串（已经存在的东西），你应该把它放在一个辅助类，或者修改框架的字符串帮助类（如果有的话）。然而，这是一个惯例或标准，但如果你正在创建一些非常酷的字符串处理功能，你可以为它创建一个库。

if i've got string functions i use a lot, should i put them in a helper class or a library class?

functions like: truncate string if longer than 30 characters, return a random string, make all lower cases and so on. these are functions that i probably don't need to create an object for. it's better to use them as static methods.

should i put them in a library class or a helper class?

when do i know when to put where?

解决方案

Helpers are the classes that help something already there for example there can be a helper for:

array
string
url
etc

A library is something that can be any solution; it could be created for the first time by you and no one else has created.

Because you are dealing with a string (something already there), you should put it in a helper class, or modify the string helper class of the framework (if there is one). However, this is a convention or standard but you can create a library for it too if you are creating something really cool for string handling with quite some functions.
