mysqli连接数据库端口

<?php
$host = 'localhost';
$user = 'your_username';
$password = 'your_password';
$database = 'your_database';
$port = 3306; // 默认端口

// 创建连接
$conn = new mysqli($host, $user, $password, $database, $port);

// 检查连接
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}
echo "连接成功";
?>

<?php
$host = 'localhost';
$user = 'your_username';
$password = 'your_password';
$database = 'your_database';
$port = 3307; // 假设你尝试连接非默认端口

// 创建连接
$conn = new mysqli($host, $user, $password, $database, $port);

// 检查连接
if ($conn->connect_error) {
    echo "连接失败: " . $conn->connect_error;
} else {
