PHP development to build an enterprise resource planning (ERP) system with quality control functions

As the scale of the enterprise continues to expand, the traditional manual operation method can no longer meet the needs of the enterprise, and a more efficient and accurate management method is required Become the pursuit of many enterprises. The enterprise resource planning (ERP) system emerged as the times require. It integrates various departments and business processes within the enterprise and provides a unified platform to achieve centralized management and efficient dispatch of resources, thereby improving the management level and competitiveness of the enterprise.

In an ERP system, quality control is a crucial module, which is responsible for managing and monitoring the quality of products to ensure product qualifications and compliance with customer needs. This article will introduce how to develop an ERP system with quality control functions through PHP language.

First of all, we need to build a product management module, including the functions of entering, querying and modifying basic product information. Here is a simple PHP code example:

<?php
// 连接数据库
$conn = mysqli_connect("localhost", "username", "password", "database");

// 添加产品信息
function addProduct($name, $price, $quantity) {
    global $conn;
    $sql = "INSERT INTO products (name, price, quantity) VALUES ('$name', $price, $quantity)";
    mysqli_query($conn, $sql);
}

// 查询产品信息
function getProduct($id) {
    global $conn;
    $sql = "SELECT * FROM products WHERE id = $id";
    $result = mysqli_query($conn, $sql);
    return mysqli_fetch_assoc($result);
}

// 修改产品信息
function updateProduct($id, $name, $price, $quantity) {
    global $conn;
    $sql = "UPDATE products SET name = '$name', price = $price, quantity = $quantity WHERE id = $id";
    mysqli_query($conn, $sql);
}
?>

Next, we need to add quality control functionality. First, we can add a column to the product table to record the quality status of the product, such as quality_status, whose value can be "qualified", "unqualified", etc. Then, we can add the following quality control functions:

// 设置产品质量状态
function setQualityStatus($id, $status) {
    global $conn;
    $sql = "UPDATE products SET quality_status = '$status' WHERE id = $id";
    mysqli_query($conn, $sql);
}

// 获取产品质量状态
function getQualityStatus($id) {
    global $conn;
    $sql = "SELECT quality_status FROM products WHERE id = $id";
    $result = mysqli_query($conn, $sql);
    $row = mysqli_fetch_assoc($result);
    return $row['quality_status'];
}

We can also filter and sort based on product quality status for generating quality reports and statistical analysis and other functions. The following is a simple example:

// 获取合格产品列表
function getQualifiedProducts() {
    global $conn;
    $sql = "SELECT * FROM products WHERE quality_status = '合格'";
    $result = mysqli_query($conn, $sql);
    $products = array();
    while ($row = mysqli_fetch_assoc($result)) {
        $products[] = $row;
    }
    return $products;
}

// 获取不合格产品列表
function getUnqualifiedProducts() {
    global $conn;
    $sql = "SELECT * FROM products WHERE quality_status = '不合格'";
    $result = mysqli_query($conn, $sql);
    $products = array();
    while ($row = mysqli_fetch_assoc($result)) {
        $products[] = $row;
    }
    return $products;
}

// 按产品质量状态进行排序
function sortProductsByQualityStatus() {
    global $conn;
    $sql = "SELECT * FROM products ORDER BY quality_status ASC";
    $result = mysqli_query($conn, $sql);
    $products = array();
    while ($row = mysqli_fetch_assoc($result)) {
        $products[] = $row;
    }
    return $products;
}

Through the above code examples, we can implement basic quality control functions and further expand and improve them as needed. Of course, in actual development, we also need to consider issues such as security, stability, and performance, such as optimizing database connections, preventing SQL injection attacks, and adding permission management.

To sum up, by using PHP language to develop the quality control function in the enterprise resource planning (ERP) system, the management level and product quality of the enterprise can be improved, helping the enterprise better adapt to market changes and enhance competitiveness. Of course, the above is just a simple example, and actual development needs to be adjusted and expanded according to specific needs. I hope this article can be helpful to PHP developers in building an ERP system with quality control functions.
