先贴代码

复制代码 代码如下:


   
        数据库相关
   

    $con = mysql_connect("localhost","root","root"); //链接数据库
        if(!$con){
            die('连接失败!' . mysql_error());       //判断是否成功
        }    
/*        if(mysql_query("CREATE DATABASE testdb",$con)){ //通过mysql_query 查询或者发送命令
            echo "创建testdb成功";                  
        }
        else{
            echo "失败原因:" . mysql_error();         //判断是否创建成功
        }
*/   
        mysql_select_db("testdb",$con);               //选择链接刚刚创建的数据库
            $sql = "CREATE TABLE Persons              
               (personID int NOT NULL AUTO_INCREMENT,
                PRIMARY KEY(personID),
                FirstName varchar(15),
                LastName varchar(15),
                Age int)
            ";                                        //Mysql 语句 创建表
        mysql_query($sql,$con);                          //执行sql语句
       
    mysql_close($con);                                //关闭mysql连接
?>
