What's new in PHP 8

PHP 8.4 introduces Property Hooks, a massive quality-of-life feature that allows you to attach custom logic directly to class properties when reading or writing them. Instead of writing separate getFirstName() or setFirstName() methods for every property, you can define 'get' and 'set' hooks right under the property declaration. This drastically reduces repetitive code while maintaining static analysis and IDE support.

PHP 8.4 Example:

class User
{
    public string $name {
        get => ucfirst($this->name);
        set (string $value) => strtolower(trim($value));
    }
}

$user = new User();
$user->name = "  JOHN DOE  ";
echo $user->name; // Outputs: John doe
