While I fully understand the purpose of the do...while construct, I just
never get used to seeing it used. (in other langs I had to deal with a
'repeat...until construct and dis-liked that also). I pretty much know
if I'm going to have to deal with a run at least once when I'm coding
and therefore code appropriately, altho I don't know in what ways I've
handled it at this very moment.
That said - here is how I would ahve done your exercise. I just find it
easier to read one's code when the conditions are declared up front
rather than after reading thru some lines not knowing when or why they run:
?
$indent = nbsp;nbsp;nbsp;;
$a = 0;
while ($a = 5)
{
echo A = $abr;
$a++;
$b = 0;
while ($b = 10)
{
echo $indent B = $bbr;
$b++;
}
}
To me - so much easier to comprehend at first glance. As soon as my eye
comes to a block of code starting with a conditional like 'while', I
readily see what makes it tick. Again I see the potential usefulness of
doing it the other way as you did in your example, but in your case
there wasn't a need for using 'do...while' since you structured it so
that there was never a case where you had to force the loop to happen
regardless of conditions.
