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 :-)
