For this PHP code exercise, create a file named odd_numbers.php. This file should contain a function named odd_numbers() which accepts one parameter. The parameter must be an array.
Given an array, odd_numbers() will return an array containing only the odd numbers from the given array in ascending order. If there are no odd numbers in the given array, odd_numbers() should return an empty array.
For example, given [3, 2, 1], odd_numbers() should return [1, 3].
Note: for this exercise, a number means a whole number or, in PHP terms, an integer value.
