数组吧，直接把数组转字符串啊

implode() 函数返回由数组元素组合成的字符串。(适合一维数组)
$arr = array('Hello', 'World', 'I', 'love', 'Shanghai');
1 echo implode(" ",$arr);//加空格
the result : Hello World I love Shanghai
2 echo implode(",",$arr);//加逗号
the result : Hello,World,I,love,Shanghai
转换数组为字符串后插入数据库就可以了。
需要PHP基础知识和数据库基础知识。
以SQL为例。使用PHP MySQL 函数可以编辑数据库。
mysql_connect() 函数打开MySQL 连接。举例
?php
$con = mysql_connect("localhost","mysql_user","mysql_pwd");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}// 一些代码...mysql_close($con);
?
mysql_connect()三个参数分别是服务器名，连接账号，连接密码。
连接之后，可以使用mysql_select_db()设置要处理的数据库，后面则是用数据库语句处理数据。SQL语法简介网页链接
就是$insert这条SQL语句的问题
echo $insert;看看语句有没有问题
检查方法将输出的SQL语句放在数据库里执行以下
标准写法
$insert = "insert into my_tab(user,psd) values('".$user."','".$psd."')":
