[Resolved] Zero fill

[sstonge]

Hey,

I'm trying to creat file names from 1 to 20, but I want them to look like this (with the 0 infront of the single digit numbers)

01,02,03,04,05,06,07,08,09,10,11,12,13,14,15,16,17,18,19,20

is there a zero fill command?

I know I can do it by checking what the number is and then add a zero in if it's less than 10 but I am hopping there is a better way.

Thanks

I found the answer!!

<? 
$Num=55; 
print str_pad($Num, 6, "0", STR_PAD_LEFT); 
?> 

This will print 000055
