Question

I have a quick question. I have a function like this:

function clean_num($num){
    return trim(trim($num, '0'), '.');
}

So when I have numbers like 85.00 and 55.00 it takes off the .00 and just returns 85 and 55.

Well I have a number 0.00 and what happens is it is returning blank. It should just say 0 but I am not getting a result at all.

How can I modify this function to get what I am looking for?

Thanks!

trim() works on both ends. To only trim on the right end, use rtrim().

function clean_num($num){
    return rtrim(rtrim($num, '0'), '.');
}
