PHP development to build an enterprise resource planning (ERP) system with customer service management functions

With the continuous expansion of enterprise scale and the increasing complexity of business scope, providing efficient customer service management has become an important part of enterprise growth and One of the keys to development. In order to achieve centralized management and automation of customer service, many companies choose to use enterprise resource planning (ERP) systems to manage their customer service processes. This article will introduce how to use PHP development to build an ERP system with customer service management functions, and provide relevant code examples.

First, we need to create a database to store customer-related data. In the MySQL database, we can execute the following SQL statement to create a table named "customers":

CREATE TABLE customers (
    id INT PRIMARY KEY AUTO_INCREMENT,
    name VARCHAR(100) NOT NULL,
    email VARCHAR(100) NOT NULL,
    phone VARCHAR(20),
    address VARCHAR(255),
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

The above code creates a table containing the customer ID, name, email, phone, address, and creation time surface. Next, we can use PHP to connect to the database and perform some basic operations. The following is a sample code:

<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "erp";

// 创建数据库连接
$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接是否成功
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 查询所有客户信息
$sql = "SELECT * FROM customers";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // 输出每行数据
    while($row = $result->fetch_assoc()) {
        echo "ID: " . $row["id"]. " - Name: " . $row["name"]. " - Email: " . $row["email"]. " - Phone: " . $row["phone"]. " - Address: " . $row["address"]. " - Created At: " . $row["created_at"]. "<br>";
    }
} else {
    echo "0 结果";
}

// 关闭数据库连接
$conn->close();
?>

In the above code, we first create a database connection and execute a simple query to obtain all customer information. Then, by looping through the result set, we print out each customer's information.

In addition to querying customer information, a complete customer service management system should also include the functions of adding, editing and deleting customers. Next, we'll describe how to implement these features.

The sample code for adding customer functions is as follows:

<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "erp";

// 创建数据库连接
$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接是否成功
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 获取通过POST请求提交的表单数据
$name = $_POST["name"];
$email = $_POST["email"];
$phone = $_POST["phone"];
$address = $_POST["address"];

// 插入新的客户信息
$sql = "INSERT INTO customers (name, email, phone, address) VALUES ('$name', '$email', '$phone', '$address')";

if ($conn->query($sql) === TRUE) {
    echo "新客户添加成功";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

// 关闭数据库连接
$conn->close();
?>

In the above code, we obtain the name, email, phone number and address of the customer in the form through a POST request, and insert this information into the database .

The functional sample code for editing customer information and deleting customers is as follows:

<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "erp";

// 创建数据库连接
$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接是否成功
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 获取通过GET请求提交的客户ID
$id = $_GET["id"];

// 根据客户ID更新客户信息
$sql = "UPDATE customers SET name='Updated Name', email='updated@email.com', phone='Updated Phone', address='Updated Address' WHERE id=$id";

if ($conn->query($sql) === TRUE) {
    echo "客户信息更新成功";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

// 根据客户ID删除客户信息
$sql = "DELETE FROM customers WHERE id=$id";

if ($conn->query($sql) === TRUE) {
    echo "客户删除成功";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

// 关闭数据库连接
$conn->close();
?>

In the above code, we obtain the ID of the customer to be edited or deleted through a GET request, and use UPDATE and DELETE statements to Update or delete corresponding customer information.

Through the above code example, we can see how to use PHP to develop an ERP system with customer service management functions. Of course, this is just a simplified example, and the development of actual systems requires more functionality and security considerations. I hope this article can provide some inspiration and reference for students developing enterprise-level ERP systems.
