Language/Type: PHP arrays tallying

Write a function named find_median that accepts an array of integers as its parameter and returns the median of the numbers in the array. The median is the number that will appear in the middle if you arrange the elements in order. Assume that the array is of odd size (so that one sole element constitutes the median) and that the numbers in the array are between 0 and 99 inclusive.

For example, the median of [5, 2, 4, 17, 55, 4, 3, 26, 18, 2, 17] is 5, and the median of [42, 37, 1, 97, 1, 2, 7, 42, 3, 25, 89, 15, 10, 29, 27] is 25.

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