Put the $i = 1 outside the loop.
$i = 1;
foreach ($months) {
// do some things
$i++;
}
Incidentally, I *really* hope you're not planning on doing:
$i = 1;
foreach ($months) {
echo "month ". $i. " is ". $months[$i]. "";
$i++;
}
if you are, I suggest you play around with
foreach ($months as $currentMonth) {
and see where it gets you :-)
Cheers
Jon

well... put $i = 1; outside your loop...?
$i = 1;
foreach ($months) {
// do some things
$i++;
}

Re: [PHP] using a counter in a foreach loop
What an embarrassing oversight. I'm sorry, I figured this one out. You
don't define the $i counter variable in the loop (DUH).
$i = 1;
foreach ($months) {
// do some things
$i++;
}
Thanks to all those who may respond before reading this
