Same length number values

[CodemasterMM]

How would I take some numbers (let's say 50, 100, and 5000) and I want to make them all in the format XXXXXXXXX (9 decimal places, like 000000050, 000000100, and 000005000). How would I search the number for the amount of decimal places and make it into that such number (I am going to have random numbers basically though, so it needs to work with 000000000 to 999999999)

Thank you for your help 🙂

Try:

$test = '50';
while ( strlen( $test ) < 9 ) $test = '0'.$test;
echo $test;

I haven't needed this yet, but I think I'd go for printf() - this is from the user contributed notes:

To have a string with leading zeros use this:
$string_i = sprintf("%04s",$value)

Gives you an output with leading zeros and 4 digits.
i.e.
0001
0002
...
0010
an so on
