This article will explain in detail what php and laravel are, and the content of the article is of high quality, so the editor will share it for you as a reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

Php refers to "hypertext preprocessor", an open source scripting language that executes on the server side. Laravel is an open source Web framework based on PHP language, which adopts the architecture model of MVC; it can help users build a perfect network APP, and every line of code can be concise and expressive.

The operating environment of this tutorial: windows7 system, Laravel6&&PHP7.1 version, Dell G3 computer.

What is php?

PHP (PHP: Hypertext Preprocessor), or "hypertext preprocessor", is a scripting language executed on the server side, especially suitable for Web development and can be embedded in HTML.

PHP grammar learned C language, absorbed the characteristics of Java and Perl to develop its own characteristic grammar, and continuously improved itself according to their strengths, such as java's object-oriented programming, the main goal of which was to allow developers to quickly write high-quality web websites.

PHP supports both object-oriented and process-oriented development and is very flexible in use.

As a high-level language, PHP is characterized by open source and belongs to C language system in the design system. It can make many beginners who have received higher education accept and complete entry-level learning quickly. It is easy to get started and easy to find a job. If the amount of data and access pressure is large, the technical solutions such as redis, mysql table partition, elasticsearch search engine, message queue write protection and php system distributed cluster deployment can be integrated to alleviate the huge pressure of data storage, service access and data retrieval.

PHP is a very suitable high-level programming language for both large and medium-sized projects. Whether it is suitable or not depends on the mastery of the project R & D team. But for larger and more complex projects, the most common php-fpm programming model shows its weakness.

In view of a series of shortcomings exposed by PHP-fpm, the most simple and reliable solution is to upgrade the high version compatible with PHP in time. The performance of PHP7.0.0 is two times higher than that of PHP5.6. In addition, the Preloading preloading mechanism provided by PHP7.4 achieves a good performance improvement by realizing part of the program's resident memory, and provides efficient JIT (Just-In-Time just-in-time compilation) operation support in PHP8.

In addition, higher-level developers can turn to more difficult php-cli programming, which can solve most system performance problems, both PHP7 and PHP8 support this mode of programming.

What is laravel?

Laravel is a concise and elegant PHP Web development framework (PHP Web Framework). It frees you from the noodle-like clutter of code; it helps you build a perfect web APP, and every line of code can be concise and expressive.

There is already a set of advanced PHP ActiveRecord implementations in Laravel-Eloquent ORM. It can easily apply "constraints" to both parties of the relationship, so that you have complete control over the data and enjoy all the conveniences of ActiveRecord. Eloquent natively supports all methods of querying constructors (query-builder) in Fluent.

Because Laravel has excellent characteristics such as Rails agile development, the deep integration of PHP's powerful Composer ecology and the broad audience of PHP developers has made Laravel develop rapidly in just a few years after its release. From the trend chart provided by Google Trends (figure 1.1), we can see that the growth rate of Laravel framework in the past seven years is the fastest in all kinds of PHP frameworks, which directly reflects the strength of Laravel and its considerable development prospects in the future.

Why is Laravel so popular?

When building a language framework, an excellent engineer should know how to coordinate the relationship between the framework and the language, and use the wisdom of his predecessors to think about the rationality and expansibility of the framework. Taylor Otwell, the author of Laravel, has certainly done this.

Experienced Web developers should have heard of a well-known Web development framework called Ruby on Rails (Rails for short). Rails is a Web development framework based on the Ruby language, which has the following principles:

Emphasize and pay attention to agile development

Convention over configuration (Convention over configuration)

DRY (Don't repeat yourself) don't repeat yourself and advocate code reuse.

Attach importance to "coding pleasure".

Since its birth, Rails has been widely concerned and discussed by the technical community. It is because Laravel combines these excellent features of the Rails framework that it is highly respected in the PHP community.

So much for sharing about what php and laravel are. I hope the above content can be helpful to you and learn more knowledge. If you think the article is good, you can share it for more people to see.
