Basic knowledge review: Why use PHP framework? _PHP Tutorial-PHP Tutorial-php.cn

There are many reasons why PHP is the most popular scripting language in the world: flexibility, ease of use, and more. But usually coding in PHP or other languages will appear monotonous and repetitive. At this time, a PHP framework is needed to replace the programmer to complete the repetitive parts. This article will provide a comprehensive analysis of the PHP framework by answering the questions What, When, Why and Which.

What is the PHP framework?

The PHP framework provides a basic framework for building web applications, thereby simplifying the process of writing web applications in PHP. In other words, the PHP framework helps promote rapid application development (RAD), which not only saves development time, helps build more stable applications, but also reduces repetitive coding development. Frameworks can also help beginners build more stable application services by ensuring proper database exchange and coding at the presentation layer. This allows you to spend more time creating actual web applications instead of writing repetitive code.

It is generally believed that the role of the PHP framework is equivalent to the model-view-controller (Model View Controller). MVC is a programming architectural pattern that separates business logic from the UI, allowing each to be modified individually (also known as separation of concerns). In MVC, Model refers to data, View refers to the presentation layer, and Controller refers to the application or business logic. Basically, MVC breaks down an application's development process so that each component can work independently without being affected. Essentially, this makes coding in PHP faster and simpler.

Why use PHP framework?

There are many benefits for developers to use PHP frameworks, one of which is to speed up the development process. Reusing code in similar projects will save developers a lot of time and effort. Frameworks provide pre-built modules for performing tedious coding tasks, so developers can spend their time developing practical applications instead of rebuilding basic functionality for every project.

Stability is another important reason why developers use frameworks. Although simplicity is the biggest advantage of PHP, and many people like to use this scripting language because of this, it is also the biggest disadvantage of PHP. Some developers, especially beginners, can easily write poor code without even realizing it. With PHP, applications tend to double the static work and before you know it you may have opened a large security hole in your coding and therefore be vulnerable to attacks. It's important to remember that PHP is a very forgiving language, so it's even more important to make sure you close any holes when programming, even if the application appears to work fine.

Finally, the use of PHP frameworks is very widespread, and there are many different frameworks to choose from. Many developers will choose a well-known framework because of its popularity, huge support from its development team, and they can communicate with other developers using the same framework through forums/communities. Of course, you can also develop your own framework. As a reminder, you should first examine your project to decide whether you should use a framework. You should ask yourself: Will it save you and other users time and energy? Will application performance be better? Will it improve stability? If you answered yes to these questions, then it’s time to choose an appropriate framework for your project.

When to use PHP framework?

This is a question common to both experienced and junior developers, and there really is no direct answer to this question. For many beginners, a framework will provide a lot of ease and stability, so PHP frameworks should be used whenever possible. This will help reduce or eliminate bad coding and speed up the development process.

On the other hand, many experienced PHP programmers view frameworks as tools for low-level programmers who don’t know how to write good, clean code. Regardless of whether this is true or not, there is no doubt that the PHP framework is a tool that can be used to save time and enhance your coding.

When working on a project that is tight on time, using the PHP framework has many benefits and can greatly speed up the coding process. Therefore, if you are tight on time, using the PHP framework is a good choice. Another example is that when you are working on a project with a lot of code, you should also consider using a PHP framework as it will help reduce the tediousness of the work.

What kind of PHP framework are you looking for?

There are many PHP frameworks for developers to choose from and even create their own, although this is only recommended for PHP experts. When looking for the PHP framework you need most, it is important to figure out who will be using or modifying your application from start to finish. If there are many people doing it, it is better to use a popular PHP framework so that most developers Neither will be unfamiliar. On the other hand, if you want to build web applications for your personal use, then it is better to choose a PHP framework that makes you happy, regardless of whether it is popular among the developer community.

There are many reference factors for choosing a PHP framework, including: ease of use, rapid development, performance, popularity among developers, powerful functions, technical support, forums, etc. When you are first choosing a PHP framework, it is recommended to try a few in order to find the best choice for your needs. Each framework is different and has different strengths and weaknesses. For example, the Zend Framework has been popular for so long due to V3 and its diverse functions and extensive support system. On the contrary, CakePHP is another PHP framework that is later than the Zend framework and has less corresponding support system, but it is more convenient and easier to use.

As you can see, each type of PHP framework has its own advantages, so it’s best to use trial and error to find out which one of them best suits your needs. Another effective way to choose a PHP framework is to consult with your colleagues and see which one is best in the development community. Those who have actually used a specific framework can definitely tell you about its ease of use, functionality, support availability, presence within the community, and of course its possible shortcomings.

Most common mistakes when using PHP frameworks

There can be mistakes in any kind of programming, but PHP frameworks help limit these mistakes significantly. Repeated coding seems to exacerbate this error, while frameworks solve this problem. Still, be careful when using any PHP framework. For example, unless you are an expert in PHP programming, you should always choose to use a popular framework that has a lot of support and an active user base. Many frameworks have little or no support, and they may have been created by individual developers with limited knowledge of PHP. These types of frameworks may prevent your application from functioning properly, or worse, may cause catastrophic security issues for your website.

Another common mistake is not ensuring that your database and web server comply with a specific framework. For example, Seagull PHP Framework recommends the following configuration:

◆PHP: The minimum is PHP 4.3.0, PHP 5.1.1 or higher is better, avoid anything in the 5.0.x version;

◆MySQL: supports MySQL 4.0.x, 4.1.x and 5.0.x, 3.23.x can also be used;

◆Apache: Seagull supports 1.3.x and Apache 2.x series.

If you don’t meet these requirements, you won’t see the best performance in your chosen framework. Even if you are a PHP expert, you should always review the framework's documentation and confirm compatibility before trying it.

Similar to the common mistakes mentioned earlier, your PHP framework can also cause you some headaches if you don't follow the recommended installation process. Taking Seagull as an example, there is a detailed framework installation process in Seagull's wiki, which contains several key steps that can easily be overlooked by careless or uninformed developers. So you'll want to take the time to install the frame and follow the installation instructions.

What are the best PHP frameworks?

In the past few years, because PHP has developed into the scripting language of choice for most developers, a large number of PHP frameworks have also been produced. What is the best PHP framework is a matter of opinion, as not every framework is suitable for everyone. Here are 5 of the best and most popular PHP framework choices:

◆The Zend Framework

The Zend Framework is popular among the developer community with its focus on Web 2.0 style applications . Zend is known as the PHP Company due to its large following, broad support, and active user base. Zend is definitely one of, if not the most popular PHP framework today. Its powerful functions can meet enterprise-level needs. Of course, its use also requires extensive PHP knowledge.

◆CakePHP

From beginners to advanced PHP developers, CakePHP is a great choice. It is designed on basically the same principles as Ruby on Rails, focusing on rapid development making it an excellent framework for rapid application development. Its rapidly growing support system, simplicity, and scalability have made CakePHP the most popular PHP framework today.

◆Symfony

Symfony is aimed more at advanced developers, that is, developers who create enterprise-level applications, especially Askeet and Yahoo! Bookmarks. This open source PHP framework is full-featured, but its main drawback is that it is slower than other frameworks.
