通过php+mysql 实现的简易blog,可以实现增删改查。效果如下图:

micro_blog

一、数据库及表结构

数据库:test

表:micro_blog(仅仅有一个表)字段:id,title,date,content,hits 表结构如下:

1CREATE TABLE `micro_blog` (
2  `id` int(20) unsigned NOT NULL AUTO_INCREMENT,
3  `title` text NOT NULL ,
4  `content` longtext NOT NULL,
5  `date` datetime NOT NULL DEFAULT '0000-00-00 00:00:00',
6  `hits` int(20) DEFAULT 0,
7   PRIMARY KEY (`ID`)
8)ENGINE=MyISAM DEFAULT CHARSET=utf8;

二、文件

文件详细描述

文件 描述
default.php 默认主页。显示博文与操作连接。
add.php 添加新博文的功能模块。
edit.php 对已经添加过的博文进行修改操作。
delete.php 删除博文模块。
view.php 显示博文的详细信息(标题|添加日期|浏览次数|内容)。
conn.php 链接数据库操作。在其它文件中被引用。

conn.php

1<?php
2//连接MySql数据库服务
3$conn = @mysql_connect("localhost:3306","root","www.361way.com") or die("连接数据库服务器失败!");
4//连接ly_php_base数据库
5@mysql_select_db("test",$conn) or die("未能连接到数据库!");
6mysql_query("SET NAMES 'UTF8'");
7?>

注:后面的set names utf8,如果不执行,会出现插入数据库中的汉字会变成乱码

default.php

 1<?php
 2include("conn.php");
 3//搜索关键字的管理
 4if(!empty($_GET['keys'])){
 5    $keys = "WHERE title like '%".$_GET['keys']."%'";
 6} else {
 7    $keys = "";
 8}
 9$sql = "SELECT * FROM micro_blog ".$keys." ORDER BY id DESC LIMIT 10";
10$query = mysql_query($sql);
11$rs = mysql_fetch_array($query);
