Formatting a number with leading zeros in PHP

I have values between 00 – 29 that need to be selected randomly using PHP.
I tried to use rand() function, but it gives me 0 – 29. not 00, 01, 02, 03 … etc.

how to get 00 – 09 instead of 0 – 9 from PHP randomly? thanks.

Answer 1

$random = sprintf("%02f", rand(0,29));

or, as mentioned in the comments:

$random = str_pad(rand(0,29), 2, "0", STR_PAD_LEFT);
