Complete Guide to Efficient Bulk Data Import in MySQL Using ThinkPHP6

Overview of Bulk Data Import with ThinkPHP6 and MySQL

Bulk data import is a common requirement in many web applications. ThinkPHP6 offers robust file upload support, and MySQL includes powerful native import capabilities, especially the LOAD DATA INFILE command. This article walks through how to integrate both for a reliable and efficient data import process.

Environment Preparation

Before starting, ensure the following prerequisites are met:

• ThinkPHP6 framework is properly installed and configured
• The database and target table schema are ready
• The upload directory has appropriate read/write permissions

Creating the Upload Form

We begin by creating a file upload interface to allow users to select the data file they want to import.

use think\facade\View;
use think\facade\Request;

public function uploadFile()
{
    return View::fetch('upload_file');
}

Handling the File Upload Logic

Once the form is submitted, we validate and store the uploaded file. Here's how to handle the uploaded file in ThinkPHP6:

public function importData()
{
    $file = Request::file('file');
    $savePath = 'public/uploads/';
    $info = $file->validate([
        'size' => 2048000,
        'ext' => 'csv,xls,xlsx'
    ])->move($savePath);

    if ($info) {
        $filename = $info->getSaveName();
        $filePath = $savePath . $filename;
        // Proceed to import logic
    } else {
        // Handle upload failure
    }
}

Executing MySQL Import Logic

After a successful upload, the next step is to execute the actual MySQL import using LOAD DATA LOCAL INFILE.

use think\facade\Db;

public function importData()
{
    // ...after upload logic
    $filename = $info->getSaveName();
    $filePath = $savePath . $filename;
    $tableName = 'your_table_name'; // Replace with your actual table

    $sql = "LOAD DATA LOCAL INFILE '{$filePath}' INTO TABLE `{$tableName}` FIELDS TERMINATED BY ','";
    Db::connect()->execute($sql);
}

Post-Import Handling

After the import, you may want to process the results further—such as logging the import or showing success messages.

public function importData()
{
    // ...previous steps

    $sql = "LOAD DATA LOCAL INFILE '{$filePath}' INTO TABLE `{$tableName}` FIELDS TERMINATED BY ','";
    Db::connect()->execute($sql);

    // Add optional post-import logic or logging here
}

Conclusion

By following these steps, you can efficiently import large datasets into MySQL using ThinkPHP6. With proper error handling and logging mechanisms, this solution becomes highly maintainable and scalable. It is ideal for scenarios such as e-commerce systems, content management platforms, and other data-intensive applications.
