Should type checking be done for every method that expects a parameter in PHP?

Type checking should be done for every method that expects a parameter in PHP to ensure that the correct type of data is being passed. This helps prevent unexpected errors and improves code reliability. By using type hints in PHP, you can specify the expected data type for each parameter, allowing PHP to automatically perform type checking.

function exampleMethod(int $param1, string $param2) {
    // Method implementation
}
