Introduction to JIT in PHP 8
PHP is the most popular web scripting language and has been available for many years. With the release of the major version of PHP 5, it has been quite stable and is a popular choice among web developers. There are almost 244 million sites built using PHP as a serverside language.
In 2020, PHP 8 was released, introducing many syntactically visible features such as attributes, named argument, and union types. All of these features are not so apparent, and according to many PHP developers, the Just-In-Time compiler (JIT) is the most important milestone. This has opened up new avenues for PHP in comparison to other languages in the market. In this article, we are going to explore how the PHP language is executed and how PHP’s recent implementation of JIT improves its performance.
