Language/Type: PHP arrays
Author: Melissa Hovik (on 2018/01/05)

Write a function named find_min that accepts an array of integers as a parameter and returns the smallest integer in the array. For example, if an array variable named $nums stored the following values:

$nums = [-1, 3, 12, 15, -4, 1, -12, 1, 8];

Then the call of find_min($nums) should return -12 since that is the smallest value in the array. You may assume that the array contains at least one element.

Function: Write a PHP function as described, not a complete program.
