如何使用PHP连接MySQL数据库？

数据库名称：NewDB1
用户名：Mark
密码：secret

我用谷歌搜索了一些解决方案，但似乎都没有。

Answer 1

使用PDO -

<?php

// turn on error reporting and display
error_reporting(E_ALL);
ini_set('display_errors', 1);

// define the user
define('USER', 'Mark');
define('PASS', 'secret');

// establish database connection
try {
    $dbh = new PDO('mysql:host=localhost;dbname=NewDB1', USER, PASS);
    $dbh->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
    $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); // make sure to turn on error reporting
}
catch(PDOException $e) {
    echo $e->getMessage(); // show any error messages.
    $errorCode = $e->getCode();
}
?>

这是关于如何理解和简化PDO的更多detailed tutorial。

Answer 2

<?php
$servername = "localhost";
$username = "Mark";
$password = "secret";

// Create connection
$conn = new mysqli($servername, $username, $password);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
?>
