捷哥之天龙八部（php连接mysql数据库）

<?php
header("content-type:text/html;charset=utf-8");
//$ip = "192.168.1.1";
//echo ip2long($ip);
//echo long2ip(-1062731519);

//1.接收数据
$username = $_POST['username'];
$password = $_POST['password'];
$repass = $_POST['repass'];
$age = $_POST['age'];

//获取当前脚本的请求时间(注册时间)
$rtime = $_SERVER['REQUEST_TIME'];

//获取客户端的IP地址（注册IP）
$rip = $_SERVER['REMOTE_ADDR'];
$rip = ip2long($rip);

//判断密码两次输入是否一致
if($password!=$repass){
exit("对不起，亲，您手又抖了吧，两次密码输入不一致，请重新输入！");
}
$password = md5($password);

//数据插入的天龙八部
//1.数据库连接
$link = mysql_connect("localhost","root","lixiaoshuai");

//2.判断错误
if(mysql_errno()){
exit("数据库连接失败:".mysql_error());
}

//3.设置字符集
mysql_set_charset("utf8");

//4.选择数据库
mysql_select_db("psd1311");

//5.准备sql语句
$sql = "insert into shop_user(username,password,age,rtime,rip) values('$username','$password',{$age},{$rtime},{$rip})";

//6.发送sql语句
$result = mysql_query($sql);

//7.处理结果
if($result && mysql_affected_rows()){
echo "恭喜您，注册成功！注册的个数：".mysql_affected_rows().";您的ID号：".mysql_insert_id();
}else{
echo "对不起，您没有注册成功！失败原因：".mysql_error();
}

//8.关闭连接
mysql_close($link);
