php连接mysql,如何用php代码将数据写入数据库?》??
连接：mysql_connect("主机","用户","密码");
mysql_select_db("数据库名");
写入数据：mysql_query("insert
into

php网站怎么添加mysql数据
首先创建 一个HTML页面userinfo_add.php，在里面输入表单，文本框，输入需要提交的到数据库的信息：
账号 姓名 年龄
页面运行结果：
创建一个PHP文件（userinfo_insert.php），用来处理页面请求的，就是具体往数据库添加数据的代码：
先获取页面数据
//通过post获取页面提交数据信息 $userId = $_POST[userId];
$userName = $_POST[userName];
$userAge = $_POST[userAge];
接下来，在连接数据库 ‘test’
//地址
$url = "127.0.0.1";
//账号
$user = "root";
//密码
$password = "root";
//连接
$con = mysql_connect($url,$user,$password);
//设置编码机
mysql_query("set names 'utf8'");
//连接数据库
mysql_select_db("test");
编写SQL，执行SQL添加数据
$sql = "insert into user_info (user_id,user_name,user_age) values('$userId','$userName','$userAge')";
if (!mysql_query($sql,$con))
{
die('Error: ' . mysql_error());
}
echo "添加一条记录";
//关闭连接
mysql_close($con)
