卓象科技:PHP文件包含的几种方式

一.简介

在我们日常写代码的时候,肯定有的时候会使用到文件包含,那我们今天就来介绍和总结一下文件包含的几种方式。


二.介绍

文件包含分为四种方式

1、include “文件”

2、include_once “文件”

3、require “文件”

4、require_once “文件”


三.总结

include在引文的时候如果在引入文件的时候出现文件不存在的情况下会出现警告错误代码继续执行。

Require在引文的时候如果出现引入失败文件不存在的情况下会出现致命错误代码不继续执行。

require_once和include_once的共同点:两个引文都会自动判断之前有没有引入此文件,如果引入了此文件则不会进行第二次引入,反之如果没有引入则引入此文件。
