PHP 实现网约车系统的基本功能

网约车系统通常包括用户端、司机端和管理后台。以下是使用 PHP 实现网约车系统的基本功能和实现方法。

数据库设计

创建数据库表结构，核心表包括用户表、司机表、订单表和车辆表。

CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(100),
    phone VARCHAR(20),
    password VARCHAR(255),
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

CREATE TABLE drivers (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(100),
    phone VARCHAR(20),
    password VARCHAR(255),
    license_number VARCHAR(50),
    vehicle_id INT,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

CREATE TABLE vehicles (
    id INT AUTO_INCREMENT PRIMARY KEY,
    plate_number VARCHAR(20),
    model VARCHAR(50),
    color VARCHAR(20),
    driver_id INT,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

CREATE TABLE orders (
    id INT AUTO_INCREMENT PRIMARY KEY,
    user_id INT,
    driver_id INT,
    pickup_location VARCHAR(255),
    destination VARCHAR(255),
    status ENUM('pending', 'accepted', 'completed', 'cancelled'),
    fare DECIMAL(10,2),
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

用户注册与登录

实现用户和司机的注册登录功能，使用 PHP 和 MySQL 处理数据。

// 用户注册示例
function registerUser($name, $phone, $password) {
    $hashed_password = password_hash($password, PASSWORD_DEFAULT);
    $sql = "INSERT INTO users (name, phone, password) VALUES (?, ?, ?)";
    $stmt = $pdo->prepare($sql);
    return $stmt->execute([$name, $phone, $hashed_password]);
}

// 用户登录示例
function loginUser($phone, $password) {
    $sql = "SELECT * FROM users WHERE phone = ?";
    $stmt = $pdo->prepare($sql);
    $stmt->execute([$phone]);
    $user = $stmt->fetch();

    if ($user && password_verify($password, $user['password'])) {
        return $user;
    }
    return false;
}

叫车功能实现

处理用户叫车请求，匹配附近司机。

function requestRide($user_id, $pickup, $destination) {
    // 创建订单
    $sql = "INSERT INTO orders (user_id, pickup_location, destination, status) VALUES (?, ?, ?, 'pending')";
    $stmt = $pdo->prepare($sql);
    $stmt->execute([$user_id, $pickup, $destination]);
    $order_id = $pdo->lastInsertId();

    // 查找附近司机
    $sql = "SELECT * FROM drivers WHERE id NOT IN (SELECT driver_id FROM orders WHERE status = 'accepted')";
    $drivers = $pdo->query($sql)->fetchAll();

    return ['order_id' => $order_id, 'available_drivers' => $drivers];
}

司机接单功能

司机接受或拒绝订单请求。

function acceptOrder($driver_id, $order_id) {
    $sql = "UPDATE orders SET driver_id = ?, status = 'accepted' WHERE id = ? AND status = 'pending'";
    $stmt = $pdo->prepare($sql);
    return $stmt->execute([$driver_id, $order_id]);
}

订单状态更新

更新订单状态为完成或取消。

function completeOrder($order_id) {
    $sql = "UPDATE orders SET status = 'completed' WHERE id = ?";
    $stmt = $pdo->prepare($sql);
    return $stmt->execute([$order_id]);
}

function cancelOrder($order_id) {
    $sql = "UPDATE orders SET status = 'cancelled' WHERE id = ?";
    $stmt = $pdo->prepare($sql);
    return $stmt->execute([$order_id]);
}

支付功能集成

集成支付网关处理费用支付。

function processPayment($order_id, $amount, $payment_method) {
    // 调用支付API
    $payment_result = callPaymentAPI($amount, $payment_method);

    if ($payment_result['success']) {
        $sql = "UPDATE orders SET fare = ?, status = 'completed' WHERE id = ?";
        $stmt = $pdo->prepare($sql);
        return $stmt->execute([$amount, $order_id]);
    }
    return false;
}

位置追踪

使用地图 API 实现实时位置追踪。

function updateDriverLocation($driver_id, $latitude, $longitude) {
    $sql = "UPDATE drivers SET latitude = ?, longitude = ? WHERE id = ?";
    $stmt = $pdo->prepare($sql);
    return $stmt->execute([$latitude, $longitude, $driver_id]);
}

function getDriverLocation($driver_id) {
    $sql = "SELECT latitude, longitude FROM drivers WHERE id = ?";
    $stmt = $pdo->prepare($sql);
    $stmt->execute([$driver_id]);
    return $stmt->fetch();
}
