We'll say i is zero, and then we'll start our loop. So this could say, do echo, i, while i is less than 10. So this loop will execute and print out the value of i, as long as i is less than 10. So we should see the numbers zero through nine, printed out on the page. But we don't. And you could see that our program is still running here. That's because we forgot one crucial part of the loop, which is the incrementor. So if we add, i++ save and refresh. Now, we have a list of numbers from zero through nine, and then our loop terminates. Do while loops are great if you want…
