What are RFC-Typehints and references, and why are they important in PHP development?

RFC-Typehints and references in PHP are important for specifying the data types of function parameters and return values, as well as for passing variables by reference. Typehints ensure that the correct data types are used, which can help prevent errors and improve code readability. References allow functions to directly modify the original variable, rather than creating a copy. Both RFC-Typehints and references are important in PHP development for maintaining code quality and consistency. 

// Example of using RFC-Typehints and references in PHP
function addOne(int &$num) {
    $num++;
}

$number = 5;
addOne($number);
echo $number; // Output: 6
