This article introduces what is HHVM and PHP7 and how to choose PHP7 and HHVM. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

PHP is one of the most popular scripting languages for web development. The latest version of PHP, PHP7 has made a lot of performance optimizations. However, PHP also has a competitor HHVM (HipHopvirtualMachine), a virtual tool that runs PHP code. The editor below explains what is HHVM and how to choose between PHP7?PHP7 and HHVM?

In 2008, Facebook launched a project to develop a tool to convert PHP scripts into Cellular scripts so that they can be compiled and run on web servers. The goal is to save server resources, which is an important goal because the number of users of Facebook is growing rapidly. In this sense, the project is successful because it allows the server to handle five to six times the previous number of requests.

Back in 2010, Facebook's server demand has increased a lot, and it's time to consider new innovations to improve efficiency. Based on this requirement, Facebook developed HHVM.

HHVM uses Just-In-Time (JIT) compilation to convert PHP code into some kind of bytecode. Then the bytecode is converted into machine code and optimized to make it run as fast as possible.

What is PHP7?

PHP7 is the response of the PHP community to HHVM. The preview version released by PHP7 claims to be 100% better than the previous PHP5.

You might ask that the version of PHP jumped directly from PHP5 to PHP7, and the answer is this: the development of PHP6 started in 2005, but its progress was too slow and there were a lot of problems, so PHP6 had a bad reputation before it was released. So the PHP community decided to name the new version of the language PHP7 directly.

The real problem is not the comparison between PHP5 and PHP7, because it is already clear that PHP7 provides faster speeds. But we want to compare PHP7 with HHVM. Many experts have used these two methods to deal with PHP code separately, and have revealed some interesting conclusions.

How should PHP7 and HHVM choose?

Before answering which is better, let's take a look at the key differences and similarities between them.

Code parsing:

The basic difference between PHP7 and HHVM is the way they parse PHP code. PHP7 uses the standard PHP parser, which is free software for everyone to use and can be parsed and run directly on the server. It generates HTML code and sends it to the client, which displays what the user expects.

By contrast, HHVM first converts PHP code into HipHop bytecode, which is then translated into machine code and then executed. In this process, HHVM will optimize the code, optimize some of the PHP code that affects the efficiency of execution, the goal is to improve the running speed.

Reasons for choosing PHP7

PHP7 is faster than HHVM in some cases, including running Drupal8. You do not need to install the setup HHVM to use PHP7. Although many of the features of PHP4 are no longer supported in the new version, code written in PHP5 will work as expected when converted to PHP7. PHP7 is developed by the PHP community, a group of people who have a long reputation for developing stable and reliable versions of PHP.

HHVMvs.PHP7: make your choice

Don't hesitate to suggest that online sites try to choose between PHP7 and HHVM and start implementing solutions early to optimize the performance of your site. An inefficient website will also damage your reputation, which will be difficult to recover.

It is more beneficial than the older version of PHP,HHVMandPHP7. Make a decision to switch your website to the new system as soon as possible.

About what is HHVM and PHP7 and how PHP7 and HHVM should choose to share here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
