PHP 8 Features that Will Upgrade Performance

PHP 8 Features

Last Updated on March 30, 2023 by Team Experts

PHP is a popular server-side programming language that is used by web developers worldwide to build dynamic websites and applications. PHP has been around for more than 25 years, and it continues to evolve with each new release. The latest release, PHP 8, comes with several features that enhance performance and improve the overall developer experience. In this article, we will take a closer look at some of the new features in PHP 8 that will upgrade performance.

JIT Compiler

The most significant improvement in PHP 8 is the introduction of a Just-In-Time (JIT) compiler. The JIT compiler is designed to optimize PHP code at runtime by compiling frequently executed code into machine code. This optimization leads to faster performance of PHP code and is especially useful for applications that require high performance, such as web applications.

Union Types

PHP 8 introduces union types, which allow developers to specify multiple types that a function can accept or return. This feature allows for more flexibility in type declarations and can help to reduce the number of errors that occur during development. 

Named Arguments

Named arguments are another new feature in PHP 8 that will help to improve performance. With named arguments, developers can specify arguments by name instead of position, making it easier to read and understand code. This feature also reduces the likelihood of errors caused by incorrect argument positioning.


Attributes are a new feature in PHP 8 that allows developers to add metadata to classes, methods, functions, and properties. This metadata can be used to annotate code with information that can be used by tools such as IDEs, code analyzers, and documentation generators. Attributes can help to improve the readability and maintainability of code, making it easier to understand and modify.

Constructor Property Promotion

Constructor property promotion is a new feature in PHP 8 that allows developers to declare and initialize class properties directly in the constructor. This feature helps to reduce boilerplate code and can lead to faster development times.

Match Expression

The match expression is a new feature in PHP 8 that is similar to the switch statement, but with a more concise syntax. The match expression allows developers to compare a value against a series of patterns and execute code based on the first matching pattern. This feature can help to reduce the complexity of switch statements and make code more readable.

Nullsafe Operator

The nullsafe operator is a new feature in PHP 8 that allows developers to safely access properties and methods on null objects. This feature can help to reduce the number of errors that occur when working with null values and can make code more robust.

New Functions

PHP 8 introduces a variety of new functions that can help to improve performance. These functions include str_contains(), which checks if a string contains another string, str_starts_with(), which checks if a string starts with another string, and str_ends_with(), which checks if a string ends with another string. These functions can help to improve the efficiency of string comparisons in PHP.

Improved Error Handling

PHP 8 introduces several improvements to error handling, including the ability to throw exceptions from error and exception handlers, and the addition of the Throwable interface, which unifies the handling of exceptions and errors. These improvements can help to make error handling more consistent and easier to manage.

Other Improvements

In addition to the features mentioned above, PHP 8 also includes a variety of other improvements aimed at improving performance, including improved performance for arrays, better support for type annotations, and improved support for the latest versions of external libraries.


Overall, PHP 8 is a significant upgrade for developers looking to improve the performance of their PHP applications. With features such as the JIT compiler, union types, named arguments, attributes, and constructor property promotion, developers can write more efficient and maintainable code in less time. As PHP continues to evolve, we can expect even more performance improvements and new features that will help developers.
