How can you use PHP DocBlocks and IDE support to help enforce data type expectations in your code?

To enforce data type expectations in your code, you can use PHP DocBlocks to explicitly declare the expected data types for function parameters and return values. IDE support can then utilize this information to provide type hints, auto-completion, and error checking, helping to catch type-related issues early in the development process. 

/**
 * Adds two integers together and returns the result.
 *
 * @param int $num1
 * @param int $num2
 * @return int
 */
function addIntegers(int $num1, int $num2): int {
    return $num1 + $num2;
}

// Usage
$result = addIntegers(5, 10); // IDE will provide type hints and error checking for the function call
