Is this just for printing to the browser? Take a look at sprintf [php.net].

[henry0]

If you want to respect the number of zero in front of each number
you could preg_replace() [php.net] by adding those zeros.

but beware you might need a switch [php.net] in order to figure if the digits are single (1,2,3 etc....)
or (10, 11, 12 etc...) or (100, 101 etc..)
and add the appropriate number of zero.

<edit>
forgot: the above will also call for a loop, since you need figuring how many numbers will be changed.
hmmm, it sounds too complicated, any other alternative?

If you want to respect the number of zero in front of each number
you could preg_replace() by adding those zeros.

Or str_pad() [uk.php.net] which can do just that. Or even sprintf as eelixduppy suggests. sprintf is more concise.

eg.

$num = 2; 
echo str_pad($num,7,'0',STR_PAD_LEFT); 
echo '='; 
echo sprintf('%07u',$num);

Note that 0000002 is essentially a string, not a number. You count like 1 2 3 4, but display it as '0000001' '0000002' '0000003' '0000004'.
