$count1 = array();
      $count1[0] = "           1";
      $count1[1] = "         2 1";
      $count1[2] = "       3 2 1";
      $count1[3] = "     4 3 2 1";
      $count1[4] = "   5 4 3 2 1";
      $count1[5] = " 6 5 4 3 2 1";
      for ($b = 1;$b <= 6;$b++)
      {
      echo $count[$b];
      echo "<br>";
      }
  why does this not work? it just goes on forever. How do i use the $b to up the count of $count[]?

Well.. lets begin..

First, arrays in most languages (and it looks like you're using PHP, and PHP is one of them) start at 0. So first, $b = 0;

Second, <= 6 is not what you think it's doing. Since we start at 0 (i.e., $count[0]), when you get up to 6 you are doing $count[6], which is out of bounds of your array. So, $b < 6;

After that.. I dunno. Looks fine to me. Im not sure what you mean it 'goes on forever' but I assume you get something you don't expect, and I will also assume that it has a lot to do with the errors in your code.

TL;DR;
for ($b = 0; $b < 6;$b++) { ... }
