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);
$sql="insert into userinfo(name,password,sex,e_mail,question,answer) values('$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 ...
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");
