PHP development of enterprise resource planning (ERP) systems that build customer relationship management functions

PHP development of enterprise resource planning (ERP) system to build customer relationship management function

In recent years, with the continuous expansion of enterprise scale and intensified market competition, the importance of enterprise resource planning (ERP) system Sexuality becomes increasingly prominent. As a comprehensive management software, the ERP system can centrally manage all aspects of an enterprise's resources, improve efficiency, and reduce costs. Among them, building the customer relationship management (CRM) function is one of the important components of the ERP system, which can help enterprises establish and maintain good relationships with customers and provide strong support for the development of enterprises. This article will focus on how to use PHP language for development and give specific code examples.

1. Database design

First, you need to design a suitable database model to store relevant data. When designing the database of the CRM module, you can create the following tables:

• customer table: stores customer information, such as customer ID, name, contact information, etc.
• contact table: stores customer contact information, such as contact ID, name, position, contact information, etc.
• deal table: stores customer transaction information, such as transaction ID, transaction date, transaction amount, etc.
• activity table: stores activity information related to customers, such as activity ID, activity name, activity date, etc.
• note table: stores customer-related note information, such as note ID, note content, etc.

2. PHP development

Next, use the PHP language for development. First, you can create a file named "erp-crm.php" and introduce the database connection configuration in the file:

<?php
// 数据库连接配置
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "erp_crm";

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

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

Then, you can create some functions in the file for CRUD operations.

• Add customer:

function addCustomer($name, $phone, $email) {
    global $conn;
    $sql = "INSERT INTO customer (name, phone, email) VALUES ('$name', '$phone', '$email')";
    if ($conn->query($sql) === TRUE) {
        echo "客户添加成功";
    } else {
        echo "客户添加失败: " . $conn->error;
    }
}

• Add contact:

function addContact($customerId, $name, $position, $phone, $email) {
    global $conn;
    $sql = "INSERT INTO contact (customer_id, name, position, phone, email) VALUES ('$customerId', '$name', '$position', '$phone', '$email')";
    if ($conn->query($sql) === TRUE) {
        echo "联系人添加成功";
    } else {
        echo "联系人添加失败: " . $conn->error;
    }
}

• Add transaction:

function addDeal($customerId, $date, $amount) {
    global $conn;
    $sql = "INSERT INTO deal (customer_id, date, amount) VALUES ('$customerId', '$date', '$amount')";
    if ($conn->query($sql) === TRUE) {
        echo "交易添加成功";
    } else {
        echo "交易添加失败: " . $conn->error;
    }
}

• Add activity:

function addActivity($customerId, $name, $date) {
    global $conn;
    $sql = "INSERT INTO activity (customer_id, name, date) VALUES ('$customerId', '$name', '$date')";
    if ($conn->query($sql) === TRUE) {
        echo "活动添加成功";
    } else {
        echo "活动添加失败: " . $conn->error;
    }
}

• Add note:

function addNote($customerId, $content) {
    global $conn;
    $sql = "INSERT INTO note (customer_id, content) VALUES ('$customerId', '$content')";
    if ($conn->query($sql) === TRUE) {
        echo "备注添加成功";
    } else {
        echo "备注添加失败: " . $conn->error;
    }
}

3. Perform action

After creating the above function, you can call it as needed to add, delete, modify, check and other operations on the CRM function. For example, you can use the following code to add a customer and a contact:

// 添加客户
addCustomer("John Doe", "123456789", "john@example.com");

// 根据客户ID添加联系人
$customerId = 1;
addContact($customerId, "Jane Smith", "Manager", "987654321", "jane@example.com");

Through the above PHP development example, we can see how to use the PHP language to build an enterprise resource planning (ERP) system with CRM functions . Through correct database design and appropriate PHP code, efficient management of customer relationships can be achieved and the competitiveness of the enterprise can be enhanced. Of course, this is just a simple example, and actual ERP systems require more detailed development and design based on specific business needs.
