?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):
2
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());
}
3
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");
