Senior programmers tell you that PHP is different today

PHP has a very high market share in the world, second only to Java, and from the data on various recruiting sites, there are many jobs in PHP development, and the salary level is very good. In fact, in small and medium-sized enterprises, Internet startups PHP's market position is higher than Java.

PHP has been around for more than more than 20 years since its inception, from the Web era to the low tide of mobile internet, various programming languages and technologies are emerging in the Internet, and node. js, go and Python are constantly challenging PHP's position. The drivers of these technologies are very keen to sing about the future of php,php language. How do PHP programmers cope with future changes?

As a veteran web back-end programming language, PHP has a very high market share in the world, after Java, and from the data on various recruitment sites, there are many jobs in PHP development, and the salary level is very good. In fact, in small and medium-sized enterprises, Internet startups PHP's market position is higher than Java. Java has a greater advantage over large enterprises, the traditional software industry, and the financial sector. For now, the languages such as node. js, GO, Python, and Ruby are hard to reach with PHP and Java.

The PHP language has its place today, thanks to the pragmatic nature of the PHP language designers, which hides the complexities of technology at the bottom. PHP Language Primer Simple, easy to master, good program robustness, not easy to appear like Java, C + + and other languages such as complex problems, such as memory leaks and Crash, tracking debugging relatively easy.

PHP is the official standard library is very powerful, a variety of functions can be found in the official standard library, including MySQL, Memcache, Redis, GD Graphics library, CURL, XML, JSON, and so on, to avoid the developers looking for libraries everywhere trouble. PHP's documentation is great, and each function has a detailed description and usage examples. Third-party class libraries and tools, code, and projects are also plentiful. Developers can quickly and efficiently write and develop various kinds of software using PHP.

So far, there is still no more easy-to-use programming language on the market than PHP. So the future of PHP is still very broad, and its struggle with the choice of programming language, it is better to learn to use PHP in depth.

As a senior PHP developer, in the technical to the PHP program a few future suggestions, I hope to be helpful to everyone.

1. Composer

The 1th is to mention composer, since composer appeared, the dependency management of PHP can become very simple. The program relies on some class libraries and frameworks, which are introduced directly using composer, to install dependent packages by using composer update. Addresses the challenges of loading external libraries in the past.

Composer also has a domestic mirror, very fast. Now the vast majority of PHP open source projects have provided composer support, it is recommended that in the project to enable composer to solve the problem of PHP code package management, do not use the download source code, manual include the original method.

2. PHP7

The PHP7 version has made a lot of changes to the Zend engine, greatly improving the performance of the PHP language, and using PHP7 can double your program performance instantly. Even the heavyweight software of WordPress, which runs at PHP7, can have thousands of QPS, which is the equivalent of a single server handling 80 million requests per day.

With PHP7, MySQL optimized, accelerated with Memcache and Redis, the technology architecture is perfectly capable of dealing with a fairly large scale system. In addition to some billion-tier users of the platform, the general scale of the system is completely free of pressure.

3. PSR

PSR is the PHP language development specification developed by Phpframework Interop Group, which has many rules, such as namespace, class name specification, coding style Standard, Autoload, public interface, etc. It has become the de facto standard for the PHP technology community. Many well-known PHP frameworks and class libraries follow the PSR specification. PHP developers should learn to master the PSR specification and should follow the PSR specification as much as possible when developing the program.

4. Swoole

2017 is PHP also limited to making Web sites? No, if you don't know swoole, get to know it. Swoole's slogan is to redefine the PHP language, Swoole is an asynchronous parallel communication engine that runs as an extension of PHP. The asynchronous callback swoole of node. JS has the swoole of the Go language, which completely overturns the knowledge of PHP. Using Swoole PHP can implement the resident memory of the server program, can implement TCP, UDP asynchronous network communication programming development.

In the past PHP can only be a Web site, now use Swoole can do Java, C + + to achieve the communication services, such as websocket even communication, chat, push server, RPC Remote Call service, Gateway, agent, game server, etc. If you want to use PHP to do something outside of the web system, Swoole is the best choice.

5. Laravel

In recent years, the hottest PHP framework, the official website is a framework designed for web artists, it can be seen how elegant this framework. Laravel provides a wealth of functional modules, API design concise, strong expression. And its community is very active, code contributors are numerous, third-party plug-ins are very large, the ecosystem is quite prosperous.

The Laravel bottom uses a lot of symfony2 components to achieve dependency management through composer. If you are still struggling with what PHP framework to use, choose Laravel. Laravel provides command-line tools based on Symfony.console, powerful, integrated with a variety of project management, automatic code generation capabilities.

6. Phar

The Java-like jar package, named Phar, is supported after PHP5.3. Used to package multiple PHP files into a single file. This feature makes it easy for PHP to package and component applications as well as Java. An application can be punched into a Phar package and put directly into the PHP-FPM to run.

With Swoole, you can execute PHP server.phar at the command line and start the server with one click. PHP's code package can be packaged into components using Phar and placed in Swoole's server container to load execution.
