how do i do this

i have some math calculation and i want to format the result so it is something like
02.00 rather than 2
12.20 rather than 12.2

 

You could use a combination of number_format() and str_pad(). The rsult will be a string:

// assuming the result is in $result
...
$formatted = str_pad(number_format($result, 2, '.', ''), 5, '0', STR_PAD_LEFT);
...
// now $formatted is a string containing the formatted result

Code (markup):

explanation: number_format() formats $result to have two decimals, a '.' as the decimal separator. The last parameter is required and indicates we will not use a thousands-separator.
str_pad() pads the resulting formatted string so it will contain five characters, use the '0' for padding, and pad on the left.

 

try this one hope this helps

$a = 2;
$new = sprintf("%02s", $a);
echo $new;

might give you an idea for the string..
