When I do this..
$a = "00";
$b = $a+6;
echo $b;
Output is 6, but I need output 06 "with leading zero". The leading zero I need if the + number ist between 1-9. I don't figured out how I can do this, I've tried everything possible, the output is always 3 or 6 or 8 without zero.
How I can do this? where is the trick?
Thank you!
