格式化显示的钱：“x” - >“x.00”？

Question

I am storing money in MySQL with float format but .00 are removed since they don't have much meaning but I want to show them to user in a correct money format using PHP.

I wrote a function which checks whether the money field has any . period otherwise add .00 .

But personally I didn't like this function so I am looking for a built-in function which can do the same job:

function formatMoney($price){
    if (strpos($price,".") > -1)
        return $price;
    else
        return $price . ".00";
}

Edit: For the people who somehow reached my question should know that money_format doesn't work on Windows Machines as it is explained here below taken from the PHP Manual:

The function money_format() is only defined if the system has strfmon capabilities. For example, Windows does not, so money_format() is undefined in Windows.

So you should use number_format in place of it. You can see my answer on how I solved this problem.

Answer 1

Why don't you use money_format ?

Example:

$price = 43;
money_format('%.2n', $price);

Answer 2

It seems money_format doesn't work on Windows machines then I had to use number_format($price,2) and it worked just perfect.

Note from PHP Manual:

The function money_format() is only defined if the system has strfmon capabilities. For example, Windows does not, so money_format() is undefined in Windows.

Answer 3

使用money_format或sprintf 。
