Is Php 7.4 Safe

PHP Programming

As a web developer, I have always been cautious about the safety and security of the programming languages I use. Recently, I have been exploring the latest version of PHP, PHP 7.4, and its safety features. In this article, I will share my personal insights and delve deep into the details to determine whether PHP 7.4 is indeed a safe choice.

Introduction to PHP 7.4

PHP 7.4 was released on November 28, 2019, and is the latest stable version of PHP at the time of writing. It brings several new features, improvements, and bug fixes to the table. But the burning question remains: is PHP 7.4 safe to use?

Increased Performance

One of the key factors that contribute to the safety of a programming language is its performance. PHP 7.4 boasts significant performance enhancements compared to its predecessors, especially in terms of speed and memory usage. This means your applications will run faster and consume fewer resources, reducing the chances of vulnerabilities due to performance-related issues.

Typed Properties

PHP 7.4 introduces the ability to declare type hints on class properties, commonly known as typed properties. This allows developers to enforce stricter type checking, reducing the risk of type-related errors and potential security vulnerabilities that can arise from them. By explicitly defining the expected types for properties, PHP 7.4 helps prevent unintended data manipulation and improves code reliability.

Improved Error Handling

Handling errors effectively is essential for building secure applications. PHP 7.4 introduces several improvements to error handling mechanisms, making it easier to catch and handle errors. With the introduction of the “Throwable” interface, developers can catch both exceptions and errors, providing better control over error handling and ensuring the application’s stability and security.

Null Coalescing Assignment Operator

The null coalescing assignment operator (??=) is another valuable addition in PHP 7.4. This operator allows developers to assign a value to a variable only if it is currently null. It simplifies null-checking operations and reduces the likelihood of null-related vulnerabilities, such as null pointer exceptions. By utilizing this operator, developers can write more robust and secure code.


After a deep dive into the safety features of PHP 7.4, it is evident that this version brings significant improvements in terms of security and reliability. With its increased performance, typed properties, improved error handling, and the null coalescing assignment operator, PHP 7.4 provides developers with the tools necessary to build safer and more secure applications.

As a web developer, I highly recommend upgrading to PHP 7.4, taking advantage of its safety features and enjoying the benefits it brings to your projects. However, it is important to note that while PHP 7.4 is safe to use, ensuring the overall security of an application requires a holistic approach that includes best practices in coding, server configurations, and thorough vulnerability testing.
