答案 0 :(得分:2)
我认为这段代码会有所帮助
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = new mysqli($servername, $username, $password,$dbname);
?>
将此代码写入html文件并将其另存为.php 我希望它有效
答案 1 :(得分:-1)
在phpmyadmin中创建一个数据库,然后在文件中记下下面的代码并用.php
扩展名保存
<?php
$db_username = "db_username"; // Your database login username
$db_password = "db_password"; // Your database login password
$db_name = "db_name"; // The name of the database you wish to use
$db_host = "db_host"; // The address of the database. Often this is localhost, but may be for example db.yoursite.com
$conn = new mysqli($db_host, $db_username, $db_password, $db_name);
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
?>
根据您的数据库详细信息设置这4个变量。如果连接无法建立,mysqli_connect_error()
会给您错误
