What does this do in a for loop? $counter+=1

I read it as if he'd come across this: for ($counter=0; $counter<$stopper; $counter+=1) { ... lots of code ... $counter+=1; } Which, I think, would increment the counter twice on each pass through. The line in the loop needs deleting. That's just how I read it.

be ware of making assumptions like that, for instance the loop could very well be: for ($counter=0; $counter<$stopper;) { // ... lots of code ... $counter+=1; } or for ($counter=0; $counter<$stopper;$counter+=1) { // ... lots of code ... } which are both valid.

Actually, I'm testing this list .. every time I post it never appears so I'm wondering whether this will / the problem's been fixed.

it got thru :-)
