The benefits of using the PHP framework are simplifying repetitive work, improving development efficiency, and enhancing code maintainability. 1. The routing management is clearer, without manual URL judgment; 2. ORM simplifies database operations and avoids duplicate SQL statements; 3. Built-in form verification and security mechanisms, such as CSRF and XSS protection; 4. Force code structure to facilitate multi-person collaboration and subsequent maintenance; 5. Provide a unified security solution to reduce vulnerability risks; 6. Strong community support makes it easier to find answers to questions. Framework helps developers focus on core functions. Laravel is suitable for rapid development, and Symfony is more suitable for large projects. Overall, using frameworks can significantly improve development efficiency and quality.

The benefit of using PHP frameworks such as Laravel or Symfony is not how "advanced" it is, but that it can help you simplify repetitive work, make code easier to maintain, and improve overall development efficiency. If you have ever written a project from scratch alone, you are likely to encounter problems such as confusing routing processing, duplicate database operations, and inadequate security considerations. At this time, using the framework is to find a good helper for yourself.

Less repetitive work, faster development speed

One of the biggest benefits of PHP framework is that it has done a lot of basic work for you. for example:

• Routing management: You only need to configure the URL and the corresponding controller method, and don’t have to write a bunch of if else to judge the path yourself.
• Database operations: Frameworks usually come with ORM (such as Laravel's Eloquent or Symfony's Doctrine). You can operate the database in an object-oriented way, instead of writing SQL statements every time.
• Form verification and security protection: For example, preventing common security issues such as CSRF attacks and XSS injection, the framework has built-in mechanisms, you only need to enable or configure them simply.

Let me give you a simple example: you want the user to register an account. If you don't use a framework, you need to manually check form fields, filter inputs, connect to databases, execute insert statements... and it is also easy to miss some security details. With Laravel, you can use FormRequest for verification and Eloquent to save data. The entire process is clear and safe.

Better structure and maintainability

Framework forces you to organize your code in a certain structure, which is especially important for multi-person collaboration. For example, Laravel uses MVC architecture, while Symfony uses component design. The benefits of this include:

• The controller is responsible for receiving requests, the model is responsible for processing data, the view is responsible for displaying results, and the division of labor is clear.
• The configuration and business logic are separated, making it more convenient to modify.
• The person who takes over the follow-up doesn’t need to spend too much time understanding your “private coding style”.

If you have taken other people's projects before, you will know how difficult it is to read without structure. The framework is like unifying everyone's "language". Although we need to learn some rules at the beginning, it saves a lot of communication costs in the long run.

Security and community support are guaranteed

Many people think that "small projects do not require frameworks", but in fact, the smaller the project, the more likely it is to cause security vulnerabilities due to negligence. The framework is designed with common attack methods in mind and provides solutions. for example:

• Automatically escape the output content to prevent XSS
• Provide an authentication mechanism to avoid session hijacking
• Built-in encryption tools, such as password hashing

And there are huge communities and documents that continue to be updated. The problem you encounter is likely to have encountered, and Google can find the answer in one go. Unlike the wheel you wrote yourself, if you make a mistake, you can only check it slowly by yourself.

In general, using PHP framework is not to "show off", but to allow you to focus more on core functions and reduce the chance of getting stuck. Laravel is more suitable for rapid development, while Symfony is more suitable for building large systems or projects that require highly customized. Which one to choose depends on the needs, but it is better to use it than not.

Basically that's it.
