It is the most mainstream and widely used PHP framework for enterprises at present, and has almost become the standard for medium and large projects. Secondly, Symfony is suitable for large enterprise applications, while CodeIgniter is suitable for small projects or performance-sensitive scenarios. The learning path should first master the core concepts of Laravel such as routing, controller, model, and views, and then go deep into advanced functions such as middleware, queues, and event systems, and practice them through actual projects such as blogs or e-commerce backends.

What are the considerations when using phpMyAdmin in a shared hosting environment?
Article Introduction：When using phpMyAdmin on shared hosting, you need to pay attention to permission limits, file size limits, security best practices, and performance impact. First of all, due to host provider restrictions, you may not be able to create or delete the database, some MySQL permissions are disabled, and if there is a "Permission Denied" error when performing an operation is usually due to insufficient permissions. Secondly, import and export files are usually limited to upload_max_filesize and post_max_size set by PHP. Most hosts are limited to less than 50MB. Larger files should consider SSH or built-in host tools. In addition, phpMyAdmin is often a target of attacks. Be sure to use a strong password, avoid using the default access path, and log out in time to ensure security. most
