Question

I was hoping someone might help with a function that given two parameters:

@param $bytes : total amount in bytes of data consumed
@param $rate : rate per GB, example .22 (for 22 cents)

@returns Total amount owed

Rounded to nearest cent of course. Thanks in advance for any help.

Answer 1

function blah($bytes, $rate) {
    return number_format($bytes / 1000000000 * $rate, 2);
}

(Alternatively, you might want to use 1073741824 as the divisor.)
