In PHP, how do I create traits with strong typing?

In PHP, you can create traits with strong typing using type declarations for methods and properties within the trait. This allows you to ensure that the data being passed and handled adheres to the specified types.

Here’s an example of how to create a trait with strong typing in PHP:


        <?php
        trait StrongTypedTrait {
            // Strongly typed property
            private int $count;

            // Constructor with strong typing
            public function __construct(int $initialCount) {
                $this->count = $initialCount;
            }

            // Method with strong typing
            public function increaseCount(int $value): void {
                $this->count += $value;
            }

            // Method with strong typing
            public function getCount(): int {
                return $this->count;
            }
        }

        class ExampleClass {
            use StrongTypedTrait;

            public function __construct(int $initialCount) {
                parent::__construct($initialCount);
            }
        }

        $example = new ExampleClass(5);
        $example->increaseCount(3);
        echo $example->getCount(); // Outputs: 8
        ?>
