Word News Online : Major Features in PHP 8.4

1. 🔄 Property Hooks

Introduces __getProperty() and __setProperty() magic methods.

Lets you hook into property access without using overloading:

php
class MyClass {
    public function __getProperty(string $name): mixed {
        // Custom logic
    }

    public function __setProperty(string $name, mixed $value): void {
        // Custom logic
    }
}

2. 🔐 Asymmetric Visibility for Class Constants

You can now define public, protected, or private get/set visibility separately:
```
php
public const string $value { get; private set; }
```

3. 🧱 Database Driver-Specific PDO Subclasses

Adds better abstraction and features for each database:
- \PDO\MySQL, \PDO\PostgreSQL, etc.
Improves type safety and provides specific driver methods.

4. 💤 Lazy Objects

Lazy initialization of objects with the new Lazy attribute:
```
php
#[Lazy]
public SomeHeavyClass $service;
```

5. 🌐 HTML5 Support in DOM Extension

Better handling of HTML5 elements in DOMDocument and related classes.
Improves parsing and encoding.

6. 📉 Deprecations

Some functions and behaviors are deprecated to clean up legacy PHP, including:

Deprecated dynamic properties (continued from 8.2).
Deprecated partially supported syntax.

7. 🧠 Miscellaneous Improvements

Performance improvements via the JIT engine.
Better error messages and stack traces.
Internal engine refinements and reduced memory usage.

🧪 Compatibility

PHP 8.4 is mostly backward-compatible with 8.3, but:

Some legacy behaviors (like dynamic properties on non-#[AllowDynamicProperties] classes) may now emit warnings or be removed.
It’s wise to test your code thoroughly before upgrading.

🔍 What is the DOM in Simple Terms?

Imagine an HTML or XML document like this:

The DOM turns that into a tree of objects:

html is the root

body is a child of html
- h1 is a child of body
  - Hello World is the text inside h1

So you can programmatically traverse, read, modify, or delete elements in the document using DOM methods.

🧰 What Is DOM Used for in PHP?

PHP has a built-in DOM extension that allows you to work with HTML and XML documents like objects, without manually parsing strings.

Example: Loading and reading an HTML document
