There are a couple of approaches to this problem, and if you really want to keep low on lines of code, you should do something like print($myAltRow = (empty($myAltRow) ? ‘odd’ : ”));
Using the fact that a variable assignment returns the assigned value in PHP here.

That’s very clever. I’ve seen this “problem” tackled in many ways, but that’s a new one to me. Nice! :)

@anonymous: Yeah, cool function as well, however in your case you’ll always HAVE to keep incrementing an $i variable. For for loops using $i, you are golden, for foreach loops over an object, its nice to not have to create another variable and increment it.

Well there’s a faster solution for this problem.
Try $row_class = $i&1?’alt’:”;
It is also very nice – just one line.

@Everyone: I think you guys are missing the beauty of this code. You can use a foreach, you can use a for..., you can have it in a while loop. Basically, all you need is one line, not three lines of if statements: $row_class = empty($row_class)? "alt" : "";
