1. Read-only classes

With PHP 8.4, it is now possible to declare entire classes as 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  the best tricks to make your campaigns go viral  we interact with object properties. This functionality  betting data  allows us to intercept access, writing, and deletion of properties using specific magic methods such as __get(), __set(), and __unset().

What does this improvement bring?

  • Allows greater control over how an object’s properties are managed.
  • Facilitates dynamic validation and logging of events related to property handling.
  • Improves encapsulation by allowing manipulation of internal logic without directly exposing it.

With this feature, PHP takes an important step towards implementing more advanced object-oriented design patterns.
