Задание 3

Make a function that will set the correct form of a noun after a number. Here's how the function should work:

phpfunc(1, 'apple', 'apples', 'apples'); // will bring out '1 apple'
func(2, 'apple', 'apples', 'apples'); // will bring out '2 apples'
func(3, 'apple', 'apples', 'apples'); // will bring out '3 apples'
func(4, 'apple', 'apples', 'apples'); // will bring out '4 apples'
func(5, 'apple', 'apples', 'apples'); // will bring out '5 apples'

Here is an example for two-digit numbers:

phpfunc(11, 'apple', 'apples', 'apples'); // will bring out '11 apples'
func(12, 'apple', 'apples', 'apples'); // will bring out '12 apples'
func(21, 'apple', 'apples', 'apples'); // will bring out '21 apple'
func(23, 'apple', 'apples', 'apples'); // will bring out '23 apples'

Our function should work for numbers of any length:

phpfunc(1223421, 'apple', 'apples', 'apples'); // will bring out '1223421 apple'
