Why do it in such a "dirty" way? Why can't you simply add an if statement to check if $i is 2 and reset it to 0, and use the conditional expression for the print-out only (which is the way it it intended to be used)?
"Perl-nerd-style" programming (which involves very very short and complex concoctions) is charming, but really hard to understand later on...

i thought it was a cool simple single-liner which i could make good use of later on.

unfortunately the conditional construct is a bit rigid. I bet you can find a strange way to force it to do what you want it to do, but it would become obscure. Anyway, if you want a recyclable single-liner... you can always make a function for it. Remember you can pass references to function, to have them act on external variables, for example to return the string, and at the same time update your $i.

Sounds like a good idea. Thanks.

You are doing it wrong way.
Take a habit using templates
So, in the getting data part write a readable code :
if ($i == 2) $row['margin'] == 'whatever';
And then in the template part:
class="customGal<?=$row['margin']?>"
