示例1: GetClosure
/**
* It returns a closure that calls the given function and validates it
* It allows the function to be called in a safe way
*
* It returns a closure that validates the parameters of the user given function
* It then calls the function
* After that it validates the return value of the function
* In case of validation errors, the closure displays an error message and ends script execution
*
* @since 1.0.0
*
* @return object $closure an object of class Closure is returned. The closure function calls the given function with the given parameters
