How can type hinting in PHP methods improve code quality and error detection, especially when using IDEs like PHPStorm?

Type hinting in PHP methods can improve code quality and error detection by specifying the expected data types of function parameters and return values. This helps developers understand the intended usage of the method and can prevent runtime errors caused by passing incorrect data types. IDEs like PHPStorm can leverage these type hints to provide better auto-completion, code navigation, and error detection during development.

// Using type hinting for method parameters and return values
function calculateTotal(int $num1, int $num2): int {
    return $num1 + $num2;
}
