How to implement a simple customer relationship management system using PHP

How to use PHP to implement a simple customer relationship management system

Introduction:
In modern business, Customer Relationship Management (CRM) plays a role plays a vital role. A good CRM system can help companies effectively manage customer information, improve customer satisfaction and increase sales opportunities. This article will introduce how to use the PHP programming language to implement a simple customer relationship management system and provide specific code examples.

1. Requirements Analysis
Before starting to write code, you first need to clarify the requirements of the system. In this simplified CRM system, we need to implement the following functions:

Customer information management: including operations such as adding customers, deleting customers, updating customer information, and viewing customer lists.
Task management: You can set tasks for customers and follow up and update the tasks.
Customer statistics: Based on the basic information of customers, calculate the number of different types of customers, age distribution and other statistical information.

2. System design
Based on demand analysis, we can design the following system architecture:

Database design: We need to create a database to store customer information and Mission information. In this simplified system, we can use MySQL as the database management system.
Interface design: We need to design a user interface so that users can operate the system conveniently. Here we will use HTML and CSS to build the user interface.
Logical design: We need to write PHP code to realize the functions of the system, including addition, deletion, modification and query of data and statistical calculations.

3. Code Implementation

Database Design
First, we need to create a database to store customer information and task information. We can create the database and corresponding tables using the following SQL statements:

CREATE DATABASE crm;

USE crm;

CREATE TABLE customers (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(50) NOT NULL,
    age INT NOT NULL,
    email VARCHAR(50) NOT NULL,
    phone VARCHAR(15) NOT NULL,
    address VARCHAR(100) NOT NULL
);

CREATE TABLE tasks (
    id INT AUTO_INCREMENT PRIMARY KEY,
    customer_id INT NOT NULL,
    task_name VARCHAR(50) NOT NULL,
    description VARCHAR(100) NOT NULL,
    deadline DATE NOT NULL,
    status ENUM('pending', 'completed') DEFAULT 'pending',
    FOREIGN KEY (customer_id) REFERENCES customers(id) ON DELETE CASCADE
);

Interface Design
Next, we need to create a user interface so that users can operate the system. We can use the following HTML and CSS code to build a simple user interface.

<!DOCTYPE html>
<html>
<head>
    <title>CRM系统</title>
    <style>
        body {
            font-family: Arial, sans-serif;
        }
        table {
            margin: 20px 0;
            border-collapse: collapse;
            width: 100%;
        }
        table th,
        table td {
            padding: 10px;
            border: 1px solid #ddd;
        }
        form {
            margin: 20px 0;
        }
        form input {
            padding: 5px;
            margin-top: 5px;
        }
    </style>
</head>
<body>
    <h1>CRM系统</h1>
    <h2>客户信息管理</h2>
    
    <form action="customer.php" method="post">
        <input type="text" name="name" placeholder="姓名" required>
        <br>
        <input type="number" name="age" placeholder="年龄" required>
        <br>
        <input type="email" name="email" placeholder="邮箱" required>
        <br>
        <input type="tel" name="phone" placeholder="电话" required>
        <br>
        <textarea name="address" placeholder="地址" required></textarea>
        <br>
        <button type="submit">添加客户</button>
    </form>

    <h2>客户列表</h2>
    
    <table>
        <tr>
            <th>ID</th>
            <th>姓名</th>
            <th>年龄</th>
            <th>邮箱</th>
            <th>电话</th>
            <th>地址</th>
            <th>操作</th>
        </tr>
        <?php
            // 在这里使用PHP代码从数据库中获取客户列表，并显示在页面上
        ?>
    </table>
</body>
</html>

Logical design
Finally, we need to write PHP code to implement the functions of the system. Here is some sample code for adding a customer and displaying a list of customers.

<?php
// 连接到数据库
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "crm";

$conn = mysqli_connect($servername, $username, $password, $dbname);

// 处理客户添加请求
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = $_POST["name"];
    $age = $_POST["age"];
    $email = $_POST["email"];
    $phone = $_POST["phone"];
    $address = $_POST["address"];
    
    $sql = "INSERT INTO customers (name, age, email, phone, address) VALUES ('$name', $age, '$email', '$phone', '$address')";
    
    if (mysqli_query($conn, $sql)) {
        echo "添加客户成功";
    } else {
        echo "添加客户失败：" . mysqli_error($conn);
    }
}

// 显示客户列表
$sql = "SELECT * FROM customers";
$result = mysqli_query($conn, $sql);

if (mysqli_num_rows($result) > 0) {
    while ($row = mysqli_fetch_assoc($result)) {
        echo "<tr>";
        echo "<td>" . $row["id"] . "</td>";
        echo "<td>" . $row["name"] . "</td>";
        echo "<td>" . $row["age"] . "</td>";
        echo "<td>" . $row["email"] . "</td>";
        echo "<td>" . $row["phone"] . "</td>";
        echo "<td>" . $row["address"] . "</td>";
        echo "<td><a href='delete.php?id=" . $row["id"] . "'>删除</a></td>";
        echo "</tr>";
    }
} else {
    echo "没有客户记录";
}

mysqli_close($conn);
?>

Copy after login

4. Summary
Through the above steps, we successfully implemented a simple customer relationship management system using the PHP programming language. This system can help us manage customer information effectively, as well as record and follow up on tasks for different customers. Of course, this is just a basic example. The actual CRM system will be more complex and needs to be expanded and optimized according to specific business needs. I hope this article will help you understand how to use PHP to implement a simple CRM system.
