1.PHP include!
语法:include "filename" 或者include_once "filename";
include功能:在执行此PHP文件之前把filename的php源码插入进来！
相当于c/c++的include,java的import源代码码导入功能！
include_once功能:在include功能的基础上，防止php文件代码重复插入的问题
样例:
//登陆网页index.php
include_once 'head.php';
include 'body.php';
include_once 'foot.php'

2.php require
语法:require "filename" 或者require_once "filename";
require功能:在include的功能基础上，添加一个如果代码错误，程序会停止运行!
require_once功能:在require功能基础上，防止php文件代码重复插入的问题!
样例:
//登陆网页index.php
require_once 'head.php';
require 'body.php';
require_once 'foot.php'

//head.php文件代码
