?php

/* 获取HTML表单提交的数据 */

$id = _POST["id"];

$catid = _POST["catid"];

$ly = array("data***");

/* 连接数据库，如果出错显示消息结束程序，否则继续执行数据库命令 */

$con = mysql_connect("127.0.0.1","user","password");

if($con == false)

{

echo "错误：系统数据库连接失败！错误信息：".mysql_error($con);

exit();

}else{

/* 选择需要操作数据库 */

mysql_select_db("mydb",$con);

/* 根据ly数组的长度决定执行多少次SQL语句 */

for($i=0;$icount($ly);$i++)

{

/* 设置SQL查询语句 */

$sql = "INSERT INTO `biaoge` VALUES('{$id}','{$catid}',".$ly[$i].")";

/* 如果SQL语句执行失败，返回错误代码； */

if(mysql_query($sql,$con) == false)

{

echo "数据库查询出错！错误代码：".mysql_errno($con);

mysql_close($con);

exit();

}

mysql_close($con);

echo "记录添加成功！";

}

至于遍历数组，有很多种方式，如楼上用的foreach语句也是可以的。这里用for的原因是为了方便提问者理解。如果代码仍有不足或不明白的地方，请您继续追问，直到给您一个满意的答复为止~

PHP操作mysql数据库的步骤

PHP访问MySQL数据库：

因为连接数据库需要较长的时间和较大的资源开销，所以如果在多个网页中都要频繁地访问数据库，则可以建立与数据库的持续连接。即调用mysql_pconnect()代替mysql_connect()。

基本步骤：

1.连接服务器：mysql_connect();

2.选择数据库：mysql_select_db();

3.执行SQL语句：mysql_query();

查询：select

显示：show

插入：insert

into

更新：update

删除：delete

4.关闭结果集：mysql_free_result($result);

5.关闭数据库：mysql_close($link);

php写mysql数据库

$sql="insert into userinfo(name,password,sex,e_mail,question,answer) values('$name','$password','$sex','$e_mail','$question','$answer')"; if(!mysql_query($sql,$con)) { echo('注册失败!'); } else { echo('注册成功!'); } 增加 SQL ...

如何用php创建mysql数据库

使用EclipsePHP Studio 3 创建一个PHP工程名称为test1,在工程名下面userinfo的文件夹，然后在文件夹创建一个PHP文件（userinfo_create.php）：

打开我们创建PHP文件：

先设置地址，账号，密码：

$url = "127.0.0.1";//连接数据库的地址

$user = "root"; //账号

$password = "root";//密码

//获取连接$con = mysql_connect($url,$user,$password);

if(!$con){

die("连接失败".mysql_error());

}

设置具体连接的数据，那我们这儿连接test数据库，我们通过Navicat 打开mysql 数据库

mysql_select_db("test");

php表单写入mysql数据库的代码

!--表单文件，拷入index.php--

!DOCTYPE html

html

head

style

label{display:inline-block;width:100px;margin-bottom:10px;}

/style

titleAdd students/title

body

!-- 数据库用mysqli 面向过程调用方法--

form method="post" action="write2db.php"

!--数据库用mysqli 面向过程调用方法
