PHP 8.3 comprehensive upgrade: performance, security, and functionality in one

The big guys in the industry have been waiting for it for a long time, and finally waited for the release of PHP 8.3 version. This version completely reconstructed PhpCore, bringing new functions and updates to PHP developers. Security features and great performance improvements. This article will introduce you to the comprehensive upgrades of PHP 8.3 in three aspects: performance, security, and new features.

1. Performance upgrade

PHP 8.3 improves memory management and garbage collection mechanism, adopts new JIT (Just In Time) compiler technology, and provides new ZTV (Zend Type Vulnerabilities) type checking system. Through these updates, the execution performance of PHP 8.3 has been improved by at least 20%.

The new JIT compiler allows PHP code to achieve better optimization and reduce function call time. In addition, PHP 8.3 uses a new machine learning algorithm to help programmers predict function call times more accurately. This helps PHP programmers adjust their code more accurately for better performance as they write it.

2. Security upgrade

In terms of security, PHP 8.3 has taken a series of measures to prevent various vulnerabilities from the source. For example:

1. Parameter filtering, type checking and verification

PHP 8.3 has optimized parameter filtering and type checking, so that developers can obtain it directly from the browser when writing code Correct parameters. This prevents malicious attackers from exploiting various vulnerabilities to gain control of the system.

2.Content Security Policy (CSP)

CSP is a technology used to defend against cross-site scripting attacks. PHP 8.3 provides developers with a more complete CSP configuration file template to help programmers better control the loading of website resources and ensure that unauthorized third-party resources are not loaded.

3. Reinforce modular code

PHP 8.3 has security hardened the modular code to prevent malicious attackers from using such code to carry out various attacks.

3. New Function Upgrade

PHP 8.3 introduces a large number of new functions and features, providing programmers with better programming tools.

1.Scalar type - PHP 8.3's new Scalar type can be limited to only accept a specific data type in parameters, avoiding developers from making type errors in class libraries when designing programs.

2. Separated namespace definition - PHP 8.3 strengthens the definition of modular code and defines the code into a clearer namespace format. It has very good application value in modular design and code reuse.

3.PHP template - PHP 8.3 introduces a new PHP language template, which is similar to the Laravel template engine and can achieve dynamic page effects more conveniently and quickly.

4. Asynchronous IO - PHP 8.3 supports multi-threading, asynchronous IO and other related technologies, allowing programmers to easily implement high-concurrency applications through PHP.

Summary

To sum up, PHP 8.3 has been fully upgraded, and significant progress has been made in performance, security, and new features. As a PHP developer, you may wish to make full use of these new features to improve your programming level and professional skills when learning and using PHP 8.3.
