That should be:

    echo sprintf('%5.2f', $a);

This means that you want two digits after the decimal point (".2"), 
and the value is to be padded on the left with spaces to achieve
a minimum of five characters ("5").

If you don't want any padding with spaces, just use %.2f as the
conversion specifier.

You might also look at PHP's round() function, which allows
rounding to other precisions.  http://www.php.net/round
