说到混编呢！像刚进入PHP学习的同志们呢应该是一脸懵的，混编？？？什么鬼。混编是一个怎么样的存在呢，接下来就由我来跟大家讲解一下吧。
对PHP的理解
PHP 是一种创建动态交互性站点的强有力的服务器端脚本语言。它可嵌入到 HTML中，尤其适合 web 开发。PHP可以包容HTML标签；实用较强。
就用学生管理这个项目来让大家熟悉一下PHP混编；
//大家通过字面量来理解PHP文件名吧！！！
首先要的创建所需要的PHP文件：
公用PHP文件
public.php；
登录注册所需要的PHP文件
login.php；logindo.php；loginout.php；register.php；registerdo.php；newpassword.php；newpassworddo.php；
学生基本信息页面所需要的PHP文件
index.php ；insert.php；insertdo.php；edit.php；editdo.php；
delete.php；mouse.php；query.php；
学生成绩管理页面所需要的PHP文件
score.php；insertscore.php；insertscoredo.php；editscore.php；editdoscore.php；deletescore.php；scorequery.php；
学生科目管理页面所需要的PHP文件
subject.php；insertsubject.php；insertsubjectdo.php；editsubject.php；editsubjectdo.php；deletesubject.php；subjectquery.php；
公用文件public.php
创建的公共的文件的目的是不用每个PHP文件连接数据库都这么麻烦，
<?php
//连接数据库
$host = 'localhost';//连接用户
$user = 'root';//数据库名称
$pass = 'root';数据库密码
$conn = mysqli_connect($host,$user,$pass);//连接数据库
if(!$conn)
{
die('连接错误:'. mysql_error(conn));//判断是否出错
}
echo '数据库连接成功';//用来测试是否连接成功
mysqli_select_db($con,'数据库名称');//选择
数据库
?>
