The use of business analysis report functions developed by PHP in enterprise resource planning (ERP) systems

Abstract:
With the continuous expansion of enterprise scale and the complexity of business, enterprises increasingly need Effective business report analysis to support management decisions. In this process, the ERP system has become an indispensable tool. This article will introduce how to use PHP to develop a set of practical business analysis report functions and provide solutions for data analysis and report display in the ERP system.

1. Introduction
   Enterprise resource planning (ERP) systems are designed to integrate business data from various departments and integrate them into a unified platform to facilitate business analysis and decision-making by business managers. The reporting function is the most important part of the ERP system. It provides managers with comprehensive and accurate data reports by sorting and analyzing corporate data. In this article, we will use PHP as the development language to introduce how to implement a practical business analysis report function.
2. Data integration
   Before developing business reporting functions, data integration needs to be performed first. ERP systems usually include data from various departments, such as sales, purchasing, inventory, etc. These data exist in different data tables. We need to integrate these data into a unified data source first to facilitate subsequent data analysis and report generation.

In PHP, we can use database operation extensions (such as MySQLi or PDO) to connect and operate the database. By writing SQL statements, we can perform related queries on the data in each table and integrate the results into a virtual table. For example, we can use the following SQL statement to integrate sales and purchasing data:

SELECT sales.*, purchases.*
FROM sales
JOIN purchases ON sales.product_id = purchases.product_id

3. Data analysis
   Once the data integration is completed, the next step is the process of data analysis. Data analysis is to process and summarize data according to business needs and generate corresponding reports. In PHP, we can use arrays and loop structures for data analysis.

For example, we want to count sales and profits every month. We can first group the data by month based on sales date and then add up sales and profits. The code example is as follows:

$data = array(); // 存储每个月的销售额和利润
foreach ($result as $row) {
    $month = date('Y-m', strtotime($row['sales_date'])); // 获取月份
    if (!isset($data[$month])) {
        $data[$month] = array('sales' => 0, 'profit' => 0);
    }
    $data[$month]['sales'] += $row['sales_amount'];
    $data[$month]['profit'] += ($row['sales_amount'] - $row['purchase_amount']);
}

4. Report Display
   After the data analysis is completed, the last step is to display the analysis results to the user in the form of a report. In PHP, we can use HTML and CSS to design report styles, and use loop structures to dynamically generate report content.

For example, we can use a table to display sales and profits for each month. The code example is as follows:

<table>
    <tr>
        <th>月份</th>
        <th>销售额</th>
        <th>利润</th> 
    </tr>
    <?php foreach ($data as $month => $values): ?>
        <tr>
            <td><?php echo $month; ?></td>
            <td><?php echo $values['sales']; ?></td>
            <td><?php echo $values['profit']; ?></td>
        </tr>
    <?php endforeach; ?>
</table>

Through the above code example, we can generate a simple and practical business analysis report. Users can select different parameters and conditions in the ERP system, and the system will generate corresponding reports based on the user's selections.

Conclusion:
Through the business analysis report function developed by PHP, various business data of the enterprise can be integrated, analyzed and displayed, providing accurate and timely data support for enterprise managers. At the same time, through flexible report design and parameter selection, users can customize appropriate reports according to their own needs, improving the efficiency and accuracy of management decision-making.
