Addition with php

problem with zero's

[dhdweb]

I have a function that takes a var and adds 1

The problem is this:
The var starts as 01, I need to add 1 and have the output be 02 and so on untill 10 when the begining 0 will be dropped.

I am still new to PHP and some help with this one.

This is what I am using now:

<? $new-var = $some-var + 01 ?>

Thanks in advance,
dhdweb

Test to see if $newvar is less then 2 digits.

if(strlen($newvar)==1)
  $newvar = "0" . $newvar;

THANK YOU

That did the trick.

$var = sprintf [php.net]("%02d", $var);

would work as well.
