Which one is better, php8.0 or php7.4?

PHP 8.0 is better than PHP 7.4 in terms of performance, functionality and security. Specific benefits include: significant performance improvements, mainly due to the JIT compiler; the introduction of new features such as concurrency support, union types and properties; and security enhancements such as eager loading and strict type checking.

PHP 8.0 vs. PHP 7.4: Which one is better?

PHP 8.0 was released in November 2020, while PHP 7.4 was released in November 2019. There are significant differences between the two, including performance, functionality, and security enhancements.

Performance

PHP 8.0 is faster than PHP 7.4. According to official benchmarks, it's over 50% faster on some tasks. This is mainly due to the introduction of JIT (just-in-time compiler), which compiles PHP code directly into machine code, thus increasing execution speed.

Features

PHP 8.0 introduces many new features, including:

• Concurrency support: allows the use of coroutines (a lightweight level threads) to write concurrent applications.
• Union type: allows variables to contain values of multiple types.
• Properties: Provides a convenient way to access the properties of a class without using getter and setter methods.

Security

PHP 8.0 has also made improvements in security, including:

• Preloading: PHP 8.0 can preload Loading files means they don't need to be interpreted when the script is run, improving performance and security.
• Strict Type Checking: PHP 8.0 introduces strict type checking, which helps prevent type errors and thereby improves the security of your application.

Choice

Whether you choose PHP 8.0 or PHP 7.4 depends on the specific requirements of your application. If you need great performance, latest features, and enhanced security, then PHP 8.0 is the better choice. However, if you have concerns about backward compatibility or your application doesn't require state-of-the-art features, PHP 7.4 is still a good choice.

It is worth noting that PHP 8.0 is still in its early stages and some libraries and extensions may not be compatible yet. If you rely on a highly customized code base, it's important to test thoroughly before upgrading.
