The function starts by using ucwords() to capitalize every word in the string. That's half of the solution; now we just need to lowercase the special cases. To find the words in the string, str_word_count() is used. When passed a format parameter of 2, this built-in function returns an array of all words in the string, referenced by their position in the string. We then need to remove the first and last elements of the array so that we don't ever lowercase them, which is easily accomplished with array_slice() ; passing it the final parameter of true makes it keep the array indices intact.

In that case, the creation of the array is not needed because the sum could just be added as the loop progresses. 6.
