I've got some code here:

$number = array(1,1.5,1.75);
for ($i = 0; $i <= 2; $i++) {
   echo "\$".$number[$i]." ";
};
?>

which returns "$1 $1.5 $1.75". However, I'd really like it to return "$1.00 $1.50 $1.75" instead. Is there some kind of PHP round function that has it return the trailing zeros in a decimal? I tried searching google, but I wasn't really so sure what to look for. Sorry if this question is way too basic.
