If you know how wide your triangle will be at the bottom, it shouldn't be too hard for you to indent the numbers at the top so that half of the numbers are left of the middle and half of them are to the right. As you are certainly aware (and a short induction shows), the count of numbers increases by one for each row you add to the bottom. The width of each number can be determined either experimentally or estimated. You will then need to output ($count_of_numbers * $number_width - $number_width_of_first_number_in_the_triangle) /s spaces to align the first row to the center, then output the first row. Then repeat the calculation for the second row of the triangle and output as many spaces as necessary before printing the numbers in the second row.
