numbers in php

[anfetienne]

Hi,

i've looked through the hp manual and cant find a function for this... is it possible to echo out double figures instead of single in php? for exmaple

    for($i=00;$i<23;$i++){
    	echo '<option value="'.$i .'">'.$i .'</option>';
    }

this lists as 1,2,3,4,5,6,7,8 ,9,10 and i want it to be 01,02,03,04,05, 06,07,08,09

is this possible?

Hey.

Check out the printf function. You can have it format the values you pass it in a number of ways, including the way you are asking.

For example:
[code=php]<?php
printf("%03d\n" , 7);
// This prints: 007
?>[/code]

Thanks Atli... that's perfect!

i tested it outside my loop and it outputs correctly but once inside my loop it still outputs single digits..... strange

[anfetienne]

i fixed it... here is my solution.... THANKS AGAIN

	for($i=0;$i<23;$i++){
    	echo '<option value="'; printf("%02d\n", $i); echo '">'; printf("%02d\n", $i); echo '</option>';
    }
