PHP using number_format and displaying the decimal point correctly

Question

My number is 495 plain and simple.

I'm trying to format this number to have it display $4.95

what I've done is number_format($number, 2, '.', '')

but that outputs 495.00

I know it can't be this difficult. Anyone familiar with number_format?

I just need it to add a decimal two numbers from the right so the cents are always displayed. ex. 4.95, 12.58, 23.39... You get the idea.

Thank you.

Whoops, my bad. Read the question wrong, if I could delete this I would! — Kenyon

Also, you should note the last two parameters in that instance are cruft (those are the defaults) — Kenyon

If you're working with integers instead of floats, you'd first have to divide by 100.

$number = 495;
echo number_format($number/100, 2, '.', '')

Assuming your numbers are all whole numbers you can do the following:

$mynum = 495;

function formatMyNum($num) {
    return $num/100;
}

Why writing function for everything when you just can divide $number by 100?

I assume you would want to reuse the logic. Personal preference I guess. A developer coming after you many not know why you are dividing by 100 so a function can be self documentation

Number format just displays floats using N number of decimals and the decimal/thousand separator characters you choose.

If you passed 4.95 to it, it would show fine so to do that just divide your $number by 100 before passing it to the function.

echo number_format($number/100, 2, '.', '');
