Whether or not the PHP framework is necessary depends on project requirements and development habits. For medium and large projects, using frameworks can improve code quality and save development time because frameworks provide standardized structures (such as MVC mode), built-in common functions (such as database operations, routing, authentication), enhanced security (such as anti-SQL injection), and integrated auxiliary tools (such as cache, queues). 1. The advantages of the framework include: standardizing code structure, improving maintenance, accelerating development speed, enhancing security, and integrating common functions. 2. The situation where the framework is not used is: small or one-time project, high-performance requirements scenarios, and basic skills practice during the learning stage. 3. When using the framework, you need to pay attention to: high learning costs, limited flexibility, and performance overhead. It is recommended to choose a suitable framework based on the project size and personal abilities and start practicing from a small project.

Is it necessary to use the PHP framework? There is actually no absolute answer to this question, it depends on your project requirements and development habits. Simply put, frameworks can help you save time and improve code quality, but they will also bring some learning costs and limitations. If you just write a simple page or gadget, there may be no need to use a framework; but if it is a medium-sized project, not using a framework may make it troublesome to maintain later.

1. What are the core advantages of the PHP framework?

The biggest role of the framework is "standardization" and "automation". It provides a set of clear structure development methods, such as the MVC (Model-View-Controller) mode, making your code easier to read and maintain. At the same time, most mainstream frameworks (such as Laravel and Symfony) have built-in functions such as database operations, routing management, and user authentication to avoid duplicate wheel creation.

For example:
If you want to implement a login function, you must handle a lot of details such as form verification, database query, session management, etc. If you use Laravel, a lot of logic can directly call ready-made methods, saving a lot of time.

Common benefits include:

• Better code organization structure
• Provide security mechanisms (such as preventing SQL injection)
• Integrate common functions (such as cache, queue, task scheduling)

2. When can I not use the framework?

Not all projects require frameworks. If your task is simple enough, such as doing a static page display, data statistics script, or just forwarding an API interface, it can be implemented using native PHP, which is lighter and faster to deploy.

In addition, if you are a novice and just start learning PHP, it is not recommended to go to the framework at the beginning. First understand the concepts of basic syntax, functions, arrays, and object-oriented, and then transitioning to a framework will make it easier to get started.

Suitable for situations where there is no framework:

• Small project or one-time script
• Extremely high performance requirements (although the gap is usually not large)
• In the learning stage, I want to practice basic skills

3. What should I pay attention to when using the framework?

The framework is good, but not omnipotent. There are several things that are easy to ignore when using:

• Learning curve : Each framework has its own rules and terms, such as Laravel's Service Provider, middleware, Facade, etc. You may feel a little dizzy when you first come into contact.
• Limited flexibility : In some scenarios, you may want to "do it your own way", but the design idea of ??the framework may not necessarily support it.
• Performance overhead : The framework itself will do more initialization work, which will have little impact on small projects, but optimization may be required in high concurrency scenarios.

suggestion:

• Don’t blindly pursue the “most popular” framework, just choose one with complete documents and active community.
• In the early stage, you can start with small projects and learn while using them.
• Pay attention to the code structure and naming specifications, and don’t write it in a mess just because you use the framework.

Basically that's it. Whether to use the PHP framework depends on the complexity of the project and personal habits. Framework is not a must, but it can help you get less trapped, especially in projects where multiple people collaborate or long-term maintenance is done.
