What's new in PHP 8.4

1. Read-only classes
With PHP 8.4, it is now possible to declare entire classes as crypto email list read-only. This means that all properties of the class will be immutable once initialized. This feature, which extends the read-only properties introduced in PHP 8.1, is ideal for creating value objects that should not be modified after construction, ensuring greater data integrity.
2. Deprecation of dynamic properties
The new version continues the transition to stricter class design by removing dynamic properties. These properties, created at runtime without prior declaration, are a common source of bugs and vulnerabilities. PHP 8.4 requires properties to be explicitly declared in classes, which improves security and makes debugging easier.
3. Property hooks
One of the most anticipated new features in PHP 8.4 is the addition of Property Hooks , a proposal that redefines how we interact with object properties. This functionality allows us to intercept access, writing, and deletion of properties using specific magic methods such as __get(), __set(), and __unset().
