How to generate mall sales reports developed by PHP

With the rapid development of the e-commerce industry, the generation of mall sales reports has become more and more important. Merchants need to analyze and make statistics on sales data in order to better understand product sales and formulate correct sales strategies. In this article, I will introduce how to use PHP to develop sales reports and provide code examples.

1. Data Collection

First, we need to collect sales data. This includes order information, product information, customer information, etc. Make sure you have a database to store this data and use appropriate table structures to organize the data. For example, we can create the following tables:

• Order table: stores order information, including order number, customer ID, product ID, quantity, etc.
• Product table: stores product information, including product ID, name, price, etc.
• Customer table: stores customer information, including customer ID, name, address, etc.

2. Order statistics

Next, we need to count sales based on the collected order data. We can use SQL queries to get the required data and store it into an array or object. Here is a sample function to get sales data for a specified time range:

function getSalesData($start, $end) {
    $query = "SELECT product_id, SUM(quantity) as total_sales FROM orders WHERE order_date >= '$start' AND order_date <= '$end' GROUP BY product_id";

    // 执行查询语句并获取结果
    $result = mysqli_query($connection, $query);
    
    // 将结果存储到数组中
    $salesData = array();
    while($row = mysqli_fetch_assoc($result)) {
        $salesData[$row['product_id']] = $row['total_sales'];
    }
    
    return $salesData;
}

In the above code, we have used the SUM function to calculate the sales data for each product within the specified time range Total sales volume.

3. Report generation

With the sales data, we can start generating reports. Reports can be presented in various forms, such as tables, charts, etc. Here, we will use HTML and CSS to create a simple tabular report.

The following is a sample function, HTML code for generating sales reports:

function generateReport($start, $end) {
    $salesData = getSalesData($start, $end);
    
    $html = '<table>';
    $html .= '<tr><th>产品ID</th><th>销售数量</th></tr>';
    
    foreach($salesData as $productId => $quantity) {
        $html .= '<tr>';
        $html .= '<td>'.$productId.'</td>';
        $html .= '<td>'.$quantity.'</td>';
        $html .= '</tr>';
    }
    
    $html .= '</table>';
    
    return $html;
}

In the above code, we first call the getSalesData function to get the sales data, and then use The loop statement populates the table with data.

4. Report Display

Finally, we need to display the generated report to merchants or other users. We can do this by outputting the HTML code of the report to the browser. The following is a sample function for displaying a sales report:

function showReport($start, $end) {
    $report = generateReport($start, $end);
    
    echo $report;
}

In the above code, we call the generateReport function to generate the HTML code of the report and pass the echo statement Output it to the browser.
