05 not 5

Anon

Hello and happy xmas!

I want $day to be e.g. 05, like 5th august. But php only saved $day like 5, and the "0" is very importen for me.

What can I do to safe the "0"?

Thank Ulrik Q K

You could do:

if ($day < 10 ) {
$day = "0$day";
}

<?
$day=5;
$day=sprintf("%02s",$day);
echo $day;
?>

Save it as a character string instead of a number:

  $day = '05';

If you later need to use it as a number, PHP will recognize that and re-cast it on the fly.

...not a good idea. Better to sAve it as an int, and format it as required.

$day = str_pad($day, 2, '0', STR_PAD_LEFT);

Why? If your using it as a string, save it as a string.

Because when PHP casts "08" or "09" to an integer, it becomes 0. (Numbers starting with '0' are interpreted in base 8. 08 is meaningless as an octal integer, so PHP Calls it a failure.)

Try it: echo 08;

Forget what I just said - it's utter cobblers. It still makes more sense to me to store it as an integer and cast it to a string when you need to, because it's more useful as an integer. But what I just said before is merely an indication I've been up far too long.

But it's not a string, it's an integer that is printed with a leading zero.

Ulrik was talking about a date remember.

Or would you prefer to store the entire date as a string?

He actually said "like 5th August".
He never said it came from a date stamp, form field, or anywhere else. Here merely asked how he could keep the value '05' instead of PHP changing it to 5.

Perhapse my misunderstanding, but I assumed he was assigning the value like:

$day = 05;
$string = $day . "th August";

and getting "5th August" when he really wanted "05th August" or something to that affect. In this case he is never using it as a numeric value and I simply sugested he do the original assignment as a character string if that is how it is being used.

Thanks to all, but this is the best I think.
