如何在modal - PHP/MySQL中检索有关特定客户端的信息

<?php
// 连接到MySQL数据库
$servername = "数据库服务器地址";
$username = "数据库用户名";
$password = "数据库密码";
$dbname = "数据库名";

$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 编写SQL查询语句
$client_id = "特定客户端ID";
$sql = "SELECT name, address, contact FROM clients WHERE client_id = '$client_id'";

// 执行SQL查询
$result = $conn->query($sql);

// 处理查询结果
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "姓名: " . $row["name"]. "<br>";
        echo "地址: " . $row["address"]. "<br>";
        echo "联系方式: " . $row["contact"]. "<br>";
    }
} else {
    echo "未找到相关客户端信息";
}

// 关闭数据库连接
$conn->close();
?>
