+ **PHP动态网站开发第二次大作业**
+
+一、选择题（6分）
+
+1、下面哪项描述是错误的？  A
+
+A.静态成员必须实例化对象才能使用
+
+B.成员变量需要用public protected private修饰，在定义变量时不再需要var关键字
+
+C.类中的普通方法只能实例化对象才能进行调用
+
+D.包含抽象方法的类必须为抽象类，抽象类不能被实例化
+
+2、关于面向对象的说法不正确的是？  D
+
+A：OOP是面向对象的简称
+
+B：静态方法不用实例化对象就能调用
+
+C：类里面的$this关键字代表该对象本身
+
+D：普通方法不用实例化对象就能调用
+
+3、面向对象的三大特性中哪个不属于封装的做法？  B
+
+A 将成员变为私有的
+
+B 将成员变为公有的
+
+C 封装方法来操作成员
+
+D 使用private修饰方法
+
+二、简答题（4分）
+
+1:面象对象的三大特性是什么?
+
+封装，继承，多态
+
+三、操作题（90分）
+
+  1、制作一个文件上传的页面，完成文件上传功能。（30分）
+
+限制规则：
+
+上传的文件不能超过1M,
+
+上传文件的类型只能是jpg、gif、png、jpeg,
+
+对上传的文件进行保存。
+
+```html
+#shang.php

+<!DOCTYPE html>
+<html lang="en">
+<head>
+    <meta charset="UTF-8">
+    <title>Title</title>
+</head>
+<body>
+<form action="chuan.php" method="post" enctype="multipart/form-data">
+    <div>
+        请选择图片进行上传：<input type="file" name="photo" id="">
+        <br>
+        <input type="submit" value="上传">
+    </div>
+</form>
+</body>
+</html>
+```
+
+
+
+```php
+#chuan.php
+<?php
+$a = $_FILES["photo"];
+
+$name = $a['name'];
+$size = $a['size'];
+
+
+$Separator = explode('.',$name); //    分割符
+
+$zh = end($Separator);//   最后一个
+
+$b = array('jpg','gif','png','jpeg');
+
+$c = in_array($zh,$b) or die("上传失败");
+
+if($size > 2*1024*1024){
+    die('大小不合适');
+}
+
+echo "上传成功";
+```
+
+2、创建如下数据库和表。（10分）
+
+ 数据库：company
+
+ 表：department
+
+| 字段名称    | 数据类型      | 约束等     | 字段描述 |
+| ----------- | ------------- | ---------- | -------- |
+| id          | int           | 主键，自增 | 部门ID   |
+| name        | varchar(32)   | 非空，唯一 | 部门名称 |
+| description | varchar(1024) |            | 部门简介 |
+
+数据如下：  
+
+![img](file:///C:\Users\acer\AppData\Local\Temp\ksohtml23900\wps5.jpg) 
+
+3、实现对部门信息数据的增删改查。（50分）
+
+查询页面如下：

+![img](file:///C:\Users\acer\AppData\Local\Temp\ksohtml23900\wps6.jpg) 
+
+新增页面如下：
+
+![img](file:///C:\Users\acer\AppData\Local\Temp\ksohtml23900\wps7.jpg) 
+

+```mysql
+mysql
+
+create database company charset utf8;
+use company;
+create table department(
+id int primary key auto_increment,
+name varchar(32) not null unique,
