This article focuses on "the introduction of PHP components, framework and Composer". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "the introduction of PHP components, frameworks and Composer".

What are components?

A component is a set of packaged code, a series of related classes, interfaces, and Trait to help us solve a specific problem in our PHP application. For example, if your PHP application needs to send and receive HTTP requests, you can use off-the-shelf components such as guzzle/guzzle implementation. We use components not to reimplement what has been implemented, but to spend more time achieving the long-term goals of the project.

Good PHP components have the following features:

Single purpose: focus on solving a problem and use simple interface encapsulation functions

Small: small and contains only the minimum amount of code needed to solve a problem

Cooperation: PHP components can work well together to achieve large-scale projects

The test is good: it provides the test itself and has adequate test coverage

Well documented: complete documentation should be provided so that developers can easily install, understand and use it.

Component vs framework

When we choose a framework, we have to invest a lot of tools in the framework. The framework usually provides a lot of tools, but when we don't provide one of the tools we need, the pain is passed on to us, and we need to find and integrate custom PHP libraries. Integrating third-party code into the framework is difficult because third-party code and the framework may not use the same interface.

When choosing a framework, we are looking at the future of the framework, but who can guarantee that a framework is always the best tool to get the job done? Large projects that have been around for many years must perform well and make adjustments all the time, which may not be possible if you choose the wrong PHP framework. Older PHP frameworks may become slow or obsolete due to a lack of community support, and these old frameworks are usually written in procedural code rather than newer object-oriented code and some of the new features of PHP. In short, there are a lot to consider when deciding whether to use the PHP framework.

Fortunately, Laravel performs well in these concerns, which is why it stands out among the many PHP frameworks. In a sense, Laravel is also a framework based on component development (the core component is its own Illuminate library, and the functional implementation relies heavily on third-party components). Compared with Symfony, it is relatively easy to use, so it is both extensible and easy to use. However, Laravel also has some shortcomings, such as Laravel's own components can not be easily decoupled for use outside the Laravel framework (but it is believed that this situation will improve, such as its database and queue components can be decoupled). Taken together, Laravel is still an excellent framework that can help us create powerful applications quickly.

At this point, I believe you have a deeper understanding of "the introduction of PHP components, framework and Composer". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
