关于class和function

Jun 23, 2016 pm 02:28 PM

例如xx.php

1.

function test() {	;}
Copy after login


2.
class class_name {	function test() {		;	}}
Copy after login


为什么都用class,是因为什么原因?


回复讨论(解决方案)

你指的是class_name?这个class类名可以随意指定,只要不是关键字即可。

Class用于声明一个类

问题没描述清楚,不知道你想问什么。。。

class类是变量与作用于这些变量的函数的集合。

PHP 4/5 使用class、function和什么都不用直接执行效率对比

PHP的Class与function之争

PHP的Class与function之争
大概看了一下,终结得出:效率差不多,个人习惯什么就用什么?

方便统一管理,和使用。

function可以实现简单的数据进出,或一系列语句组织成类似批处理
class可以实现嵌套、组合,用物理的词就是可以串联、并联,这样的话可以做的事就很多了

class多人使用是因为可以多个人分工,各自写一个class,在使用时还能组合在一起,至于人家写的class,只需要关心进出数据及其格式就足够了,这样对并行开发效率更高

不过如果只是一个人开发或者团队的合作性很高,也未必一定要用面向对象(class)这种方式,可能面向过程也很快。视乎需要吧
