printf formating

[Anon]

Hiya All

I have a counter the goes from 0 to 15 and I want to write a printf statement the print

r plus my number from the counter. For example if my counter is equal 12 then I want printf to print r12. I am using

printf("r%d",$c);

it works ok if the number is >= 10 but if the number is < 10 then it prints r1, r2, etc. I want printf to add an extra zero for me so I can get r01, r02, r03 etc. I am sure it possible but it needs a quru to do it not me. Can any one help

<?php
for ($c=0;$c <= 15; $c++) {
if ($c < 10) {
printf('r0%s<br>', $c);
}
else {
printf('r%s<br>', $c);
}
}

?>

Hi OOzy
Im not cool at php, but if the syntax is the same as c++ printf, you can use the 0-flag(zero) and the width-flag for padding with zeroes.
printf("r%02d",$c);
