问题描述

有人可以帮我解决这个问题.

hi could someone assist me in this issue.

这是我的连接字符串:

<?php

    #FileName = "Connection_php_mysql.htm"
    #Type = "MYSQL"
    #HTTP = "true"

    $hostname_Main_DB = "localhost";
    $database_Main_DB = "mydb";
    $username_Main_DB = "root";
    $password_Main_DB = "";

    $con = new mysqli_connect($hostname_Main_DB,$username_Main_DB. $password_Main_DB, $database_Main_DB) or die ( "Failed to connect to MySQL: " . mysqli_connect_errno());     $db=mysqli_select_db($database_Main_DB,$con) or die( "Failed to connect to MySQL: " .     mysqli_connect_errno());
?>

我已经安装了wamp服务器并启用了mysqli扩展名.

I have installed wamp server and mysqli extension is enabled.

希望您能够为我解决这个问题，

    $database_Main_DB = "mydb";
    $username_Main_DB = "root";
    $password_Main_DB = "";

    $con = mysqli_connect($hostname_Main_DB,$username_Main_DB,$password_Main_DB, $database_Main_DB) or die ( "Failed to connect to MySQL: " . mysqli_connect_errno());

    $db=mysqli_select_db($database_Main_DB,$con) or die( "Failed to connect to MySQL: ".mysqli_connect_errno());
?>
