Layui是一個(gè)前端UI框架,它本身并不提供連接MySQL數(shù)據(jù)庫(kù)的功能。要連接MySQL數(shù)據(jù)庫(kù),你需要使用后端編程語(yǔ)言(如PHP、Python、Node.js等)來(lái)實(shí)現(xiàn)。這里以PHP為例,提供一個(gè)簡(jiǎn)單的示例來(lái)說(shuō)明如何使用Layui與MySQL數(shù)據(jù)庫(kù)進(jìn)行交互。
connect_mysql.php
),并在其中編寫以下代碼來(lái)連接MySQL數(shù)據(jù)庫(kù):<?php
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_dbname";
// 創(chuàng)建連接
$conn = new mysqli($servername, $username, $password, $dbname);
// 檢測(cè)連接
if ($conn->connect_error) {
die("連接失敗: " . $conn->connect_error);
}
echo "連接成功";
$conn->close();
?>
請(qǐng)將your_username
、your_password
和your_dbname
替換為你的MySQL數(shù)據(jù)庫(kù)的實(shí)際用戶名、密碼和數(shù)據(jù)庫(kù)名。
