Well, elegance, is in the eye of the beholder !!.. but ya, i certainly wasnt contesting the modulas solutiion, ive used mod in similar cases myself, i was just adding some variety.

Re: [PHP] Loop within Loop help please
well, actually, the code resets the count var, so it makes absolutely no
difference how many iterations the loop makes, it could iterated
indefinately and still function identically.

You missed the $count = 0;
right below it Andrew... his code works just like the modulus one...

The only thing wrong with this method is that it doesn't fit the
problem's specifications.The original poster wanted a way to
trigger the code every 20 iterations of an unknown sized loop
(implying that the loop would have 40 or more items), whereas the
solution above only triggers it on iteration 20. Other than that,
it's a perfectly wonderful piece of code.
You left this line out of Jason's post when you snipped it
$count = 0;
ie, everytime $count reached 20, run special code, and reset count to $20.

That would be fine, but im afraid in my effort to make the example
simple i forgot to ad a line:
$count++; ;-)

I see lots of references to modulus, which works fantastic.. but how
abut just testing if its equal to 20, then there isnt that extra
arthmitc call.. this is just another way to do the same thing.. take
your pick.. unless someone can see a bad reason for this method.
$count = 0;
foreach . {
if($count == 20) {
.
$count = 0;
} else {
$count++;
}
