Be aware, since PHP 7.3 this method is deprecated and from PHP 7.4 this launch a deprecated error, so, setup your PHP web server to untrack E_DEPRECATED error reporting.

Using the money_format function with float values which have more than two decimal digits can result in rounding errors.
Maybe this function will help you to avoid these failures:

<?php
// A product with a base price of 12.95
$price = 1295;

// The quantity is also an integer but translated it would be 11.91
$quantity = 1191;

// Result: 154.2345
// It's the same like 12.95 * 11.91
$sum = ($price / 100) * ($quantity  /100);

// Wrong result: 154.23
money_format('%!i', $sum);

// Wrong result: 154.23
number_format($sum, 2);

// Wrong result: 154.23
bcmul($price / 100, $quantity / 100, 2);

// Correct result : 154.24
money_format_rounded('%!i', $sum);

Improvement to Rafael M. Salvioni's solution for money_format on Windows: when no currency symbol is selected, in the formatting, the minus sign was also lost when the locale puts it in position 3 or 4. Changed $currency = '';  to: $currency = $cprefix .$csuffix;

function money_format($format, $number) {
        $regex = '/%((?:[\^!\-]|\+|\(|\=.)*)([0-9]+)?' .

            $flags = array(
                'fillchar' => preg_match('/\=(.)/', $fmatch[1], $match) ?

For most of us in the US, we don't want to see a "USD" for our currency symbol, so '%i' doesn't cut it.  Here's what I used that worked to get what most  people expect to see for a number format.

$number = 123.4
setlocale(LC_MONETARY, 'en_US.UTF-8');
money_format('%.2n', $number);

output:
$123.40

That gives me a dollar sign at the beginning, and 2 digits at the end.
kaigillmann at googlemail dot com 12-Jun-2014 07:24
If you get "EUR" instead of the euro symbol, set the locale to utf8 charset like this:

<?php
setlocale
(LC_MONETARY, 'de_DE.utf8');
echo
money_format('%+n', 1234.56);
?>

In Rafael M. Salvioni function localeconv(); returns an invalid array in my Windows XP SP3 running PHP 5.4.13 so to prevent the Warning Message: implode(): Invalid arguments passed i just add the $locale manually. For other languages just fill the array with the correct settings.

<?

       $locale = array(
        'decimal_point'        => '.',
        'thousands_sep'        => '',
        'int_curr_symbol'    => 'EUR',
        'currency_symbol'    => '€',
        'mon_decimal_point'    => ',',
        'mon_thousands_sep'    => '.',
        'positive_sign'        => '',
        'negative_sign'     => '-',
        'int_frac_digits'    => 2,
        'frac_digits'        => 2,
        'p_cs_precedes'        => 0,
        'p_sep_by_space'    => 1,
        'p_sign_posn'        => 1,
        'n_sign_posn'        => 1,
        'grouping'            => array(),
        'mon_grouping'        => array(0 => 3, 1 => 3)
       
    );

To drop zero value decimals, use the following:
<?php
   
/*
        Same as php number_format(), but if ends in .0, .00, .000, etc... , drops the decimals altogether
        Returns string type, rounded number - same as php number_format()):
        Examples:
            number_format_drop_zero_decimals(54.378, 2) ==> '54.38'
            number_format_drop_zero_decimals(54.00, 2) ==> '54'
     */
   
function number_format_drop_zero_decimals($n, $n_decimals)
    {
        return ((
floor($n) == round($n, $n_decimals)) ? number_format($n) : number_format($n, $n_decimals));
    }
?>
Results:
number_format_drop_zero_decimals(54.377, 2) ==> 54.38
number_format_drop_zero_decimals('54.377', 2) ==> 54.38
number_format_drop_zero_decimals(54.377, 3) ==> 54.377

number_format_drop_zero_decimals(54, 2) ==> 54
number_format_drop_zero_decimals(54, 3) ==> 54
number_format_drop_zero_decimals(54 + .13, 2) ==> 54.13

We found that after switching from Ubuntu 10.04 php -v 5.3.2, to Ubuntu 12.04 php -v 5.3.10 this no longer worked:

<?php setlocale(LC_MONETARY, 'en_US'); ?>

Found that using:

<?php setlocale(LC_MONETARY, 'en_US.UTF-8'); ?>

worked find

Hi,

For South Asian Currencies, this function could be a handy one.

It will handle negative as well as float(Paise).

<?php
function my_money_format($number)
{
    if(
strstr($number,"-"))
    {
       
$number = str_replace("-","",$number);
       
$negative = "-";
    }
   
   
$split_number = @explode(".",$number);
   
   
$rupee = $split_number[0];
   
$paise = @$split_number[1];
   
    if(@
strlen($rupee)>3)
    {
       
$hundreds = substr($rupee,strlen($rupee)-3);
       
$thousands_in_reverse = strrev(substr($rupee,0,strlen($rupee)-3));
        for(
$i=0; $i<(strlen($thousands_in_reverse)); $i=$i+2)
        {
           
$thousands .= $thousands_in_reverse[$i].$thousands_in_reverse[$i+1].",";
        }
       
$thousands = strrev(trim($thousands,","));
       
$formatted_rupee = $thousands.",".$hundreds;
       
    }
    else
    {
       
$formatted_rupee = $rupee;
    }
   
    if((int)
$paise>0)
    {
       
$formatted_paise = ".".substr($paise,0,2);
    }
   
    return
$negative.$formatted_rupee.$formatted_paise;

}
?>

This function divides integer value by commas. F.e.

echo formatMoney(10059240.42941, true); # 10,059,240.43
echo formatMoney(13245); # 13,245

function formatMoney($number, $fractional=false) {
    if (
$fractional) {
       
$number = sprintf('%.2f', $number);
    }
    while (
true) {
       
$replaced = preg_replace('/(-?\d+)(\d\d\d)/', '$1,$2', $number);
        if (
$replaced != $number) {
           
$number = $replaced;
        } else {
            break;
        }

If money_format doesn't seem to be working properly, make sure you are defining a valid locale.  For example, on Debian, 'en_US' is not a valid locale - you need 'en_US.UTF-8' or 'en_US.ISO-8559-1'.

This was frustrating me for a while.  Debian has a list of valid locales at /usr/share/i18n/SUPPORTED; find yours there if it's not working properly.

Consider formatting currency for some South Asian countries that use ##,##,###.## money format.
The following code generates something like Rs. 4,54,234.00 and so on.

<?php
function convertcash($num, $currency){
    if(
strlen($num)>3){
           
$lastthree = substr($num, strlen($num)-3, strlen($num));
           
$restunits = substr($num, 0, strlen($num)-3); // extracts the last three digits
           
$restunits = (strlen($restunits)%2 == 1)?"0".$restunits:$restunits; // explodes the remaining digits in 2's formats, adds a zero in the beginning to maintain the 2's grouping.

           
$expunit = str_split($restunits, 2);
            for(
$i=0; $i<sizeof($expunit); $i++){
               
$explrestunits .= (int)$expunit[$i].","; // creates each of the 2's group and adds a comma to the end
           
}   

           
$thecash = $explrestunits.$lastthree;
    } else {
          
$thecash = $convertnum;
    }
   
    return
$currency.$thecash.".00"; // writes the final format where $currency is the currency symbol.
}
?>

now call the function as  convertcash($row['price'], 'Rs '); // that's the price from the database I called using an Indian Rupees prefix where the price has to be a plain number format, say something like 454234.

This is a handy little bit of code I just wrote, as I was not able to find anything else suitable for my situation.
This will handle monetary values that are passed to the script by a user, to reformat any comma use so that it is not broken when it passes through an input validation system that checks for a float.

It is not foolproof, but will handle the common input as most users would input it, such as 1,234,567 (outputs 1234567) or 1,234.00 (outputs 1234.00), even handles 12,34 (outputs 12.34), I expect it would work with negative numbers, but have not tested it, as it is not used for that in my situation.

This worked when other options such as money_format() were not suitable or possible.

<?php
///////////////
// BEGIN CODE convert all price amounts into well formatted values
function converttonum($convertnum,$fieldinput){
       
$bits = explode(",",$convertnum); // split input value up to allow checking
       
       
$first = strlen($bits[0]); // gets part before first comma (thousands/millions)
       
$last = strlen($bits[1]); // gets part after first comma (thousands (or decimals if incorrectly used by user)
       
       
if ($last <3){ // checks for comma being used as decimal place
           
$convertnum = str_replace(",",".",$convertnum);
        }
        else{
// assume comma is a thousands seperator, so remove it
           
$convertnum = str_replace(",","",$convertnum);
        }
       
       
$_POST[$fieldinput] = $convertnum; // redefine the vlaue of the variable, to be the new corrected one
}

@
converttonum($_POST[inputone],"inputone");
@
converttonum($_POST[inputtwo],"inputtwo");
@
converttonum($_POST[inputthree],"inputthree");
// END CODE
//////////////

?>

This is suitable for the English usage, it may need tweaking to work with other types.

Double check that money_format() is defined on any version of PHP you plan your code to run on.  You might be surprised.

For example, it worked on my Linux box where I code, but not on  servers running  BSD 4.11 variants. (This is presumably because strfmon  is not defined - see note at the top of teis page). It's not just a windows/unix issue.
