Sum fun

[mdomel]

Sorry if this has been done, but I couldn't find it here.

I need to have a number, add 1 to it for one result and subtract 1 for another. But I need the 1 value to be 001, the ten value to be 010, and etc up to 999. (I'll work in the stop later)

if ($pc != "001") {
$pcp = $pc - 1;
$pcn = $pc + 1;
}
else {
$pcp = "001";
$pcn = $pc + 1;
}

What that gives me for $pcn if $pc = 001 is 2. I need it to be 002. I've dug through my notes and through this help doc I got at php.net, but I can't find anything helpful.

I know it's silly, but it's for a file naming convention that works great elsewhere.

Thanks

Here it is:

if($pc != 1) {
$pcp = sprintf("%'03s",($pc - 1));
} else {
$pcp = "001";
}
$pcn = sprintf("%'03s",($pc + 1));

Have fun...

That's perfect, thanks.

Php is easy, why couldn't I have figured this out myself?! lol, I wish I had learned C before trying to learn php.

Yeah, I wish I had learned C, too... ;-)
