The Latest Improvements & Features Added

All the new features in PHP Development are updated without having to spend hours troubleshooting. Since PHP 8 is currently in its active development let’s start with the new features and improvements you can find in PHP 8:

1. PHP JIT (Just in Time) Compiler

JIT, also referred to as Just in Time adds a huge improvement in the version. JIT is incorporated as an independent part of the OPcache and is the most notable feature in the JIT compiler. Among all other new features added, it significantly tends to improve the performance of PHP versions.

PHP has not complied, it is interpreted line by line, but the JIT compiler compiles parts of the code during run-time which leads to the massive improvement in the performance. And when it comes to tasks like 3D rendering, data analysis, and Artificial Intelligence it makes a huge difference.

2. New Union Types

Types are an integral part of PHP, where you can assign a variable as an integer, boolean or null. Earlier it was assigned with a single type. But with PHP 8 you can assign with 2 or more types i.e a union type.

Earlier PHP Doc annotations were used to make something like union type, but now you can skip the tedious task and assign variables with multiple types.

3. High-Quality Codes

One of the most important aspects of PHP is quality codes that make a huge difference. A lot of problems remain hidden as the PHP version does not catch and highlight the errors and warnings which ultimately ends up with a lot of problems for the developers.

With the latest PHP 8 version, there is a great improvement as the developers can rectify the issues instantly and easily. However, set display_errors=Offif you decide to use PHP 8 on a live site to not show such errors to your site visitors.

4. Faster Code Execution

Although the latest version brings a lot of new things we are convinced with the fast code execution. As already discussed above the JIT simply generates a machine code as an output. This is the first time PHP came with a compiler.

With the latest features, you can analyze the improvements in the code and execute complex tasks and algorithms instantly bringing whole new opportunities to broaden its reach.

PHP version of the site can be changed from control panel-Site Tools>Dev Section or cPanel>PHP version. PHP holds WordPress together as glue therefore it’s important to keep it updated.
