# Php 8.4 Asymmetric Visibility Explained In Detail

**[Community Picks](https://daily.dev/sources/community)** · 3 min read · 25 upvotes · 4 comments

## Summary

PHP 8.4 introduces a unique feature known as Asymmetric Visibility, allowing different read and write access levels for class properties. This feature enhances encapsulation by permitting properties to be read publicly while restricting write access to the class or its subclasses. Traditional visibility levels like Public, Private, and Protected are also discussed. The syntax and crucial rules for implementing Asymmetric Visibility are outlined, emphasizing its exclusive availability in PHP 8.4 and later versions.

> Only this "private(set)" which is totally unnecessary, messed up the syntax. Only "public private $..." was necessary.
