Format a number with PHP to always have 2 digits before decimal

I'm trying to format a number in PHP to always have at least 2 places before the decimal and can't seem to figure it out no matter what I google/try. I'd prefer to only do this if there's not a whole number before the decimal.

This would be the ideal desired output, as I do not know the numbers before hand, it changes per page.

0.59 becomes 00.59
1.00 stays 1.00
0.43 becomes 00.43
14.56 stays 14.56

Any ideas?

If you're not on Windows, this works:

$num = 0.59;
echo trim(money_format("%=0#2.2n", (float)$num));

You might also need to add the ! flag if you get the currency symbol in the output.

See php.net/money_format

Add a 0 if the number is less than 1:

$res = (($num < 1) ? '0' : '').number_format($num, 2);

Here's a way to do what you want :

$num = 0.342;
$num = number_format(round((float) $num, 2),2);
if ($num < 1) $num = str_pad($num,5,'0',STR_PAD_LEFT);
echo $num;
