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.
money_format
(PHP 4 >= 4.3.0, PHP 5, PHP 7)
money_format — Formattazione di un numero come stringa monetaria
Descrizione
money_format() restituisce una versione formattata di
number. Questa funzione è un'interfaccia alla funzione C
strfmon(), con la differenza che questa funzione
converte un solo numero alla volta.
Nota:
La funzione money_format() esiste solo se il sistema suppporta strfmon. Ad esempio, Windows non lo supporta perciò la funzione money_format() non è definita su Windows.
LA specifica del formato consiste nella seguente sequenza:
un carattere
%un flag opzionale flags
la lunghezza del campo, opzionale
la precisione a sinistra, opzionale
la precisione a destra, opzionale
un carattere di conversione, obbligatorio
Flag
Si possono utilizzare uno o più dei seguenti flag:
-
=f -
Il carattere
=seguito da un singolo carattere (singolo byte) f è utilizzato come carattere di riempimento numerico. Il carattere di default è lo spazio. -
^ -
Disabilita l'utilizzo del raggruppamento dei caratetrei (come definito nelle impostazioni locali).
-
+oppure( -
Specifica lo stile di formattazione per i numeri positivi e negativi. Se si utilizza
+, sarà utilizzato l'equivalente valore locale per+e-. Se si utilizza(, i valori negativi saranno racchiusi tra parentesi. Se non si da specifica, il default è+. -
! -
Sopprime il simbolo della moneta nella stringa di output.
-
- -
Se presente, rende tutti i campi giustificati a sinistra (riempiti a a destra), il default prevede i campi allineati a destra (riempiti a sinistra).
Dimensioni del campo
- w
-
Una stringa numerica che specifica la lunghezza minima del campo. Il campo sarà allineato a destra a meno di non avere impostato il flag
-. Il valore di default è 0 (zero).
Precisione a sinistra
-
#n -
Sono attesi un numero massimo di (n) numeri a sinistra del carattere decimale (es. il punto decimale). Solitamente si utilizza per mantenere allineato l'output nella medesima colonna, utilizzando il carattere di riempimento, se il numero delle cifre è inferiore a n. Se il numero delle cifre è superiore a n, questa specifica viene ignorata.
Se il raggruppamento delle cifre non è soppresso tramite
^, saranno inseriti i separatori di raggruppamento prima dei caratteri di riempimento (se presenti). I separatori di gruppo non saranno applicati ai caratteri di riempimento, anche se il carattere di riempimento è un numero.Per garantire l'allineamento, ogni carattere che, nella stringa formattata, appare prima o dopo il numero, tipo il simbolo della moneta o il segno, viene riempito con gli spazi necessari affinché la corrispondente stringa risultante da un valore positivo o negativo abbia la medesima lunghezza.
Precisione di destra
-
.p -
Un punto seguito da un numero di cifre (p) dopo il carattere decimale. Se il valore di p è 0 (zero), il carattere decimale e le cifre alla sua destra saranno omesse. Se non vi è indicazione della precisione a destra, il default sarà preso della impostazioni locali. L'importo sarà arrontondato alle cifre decimali richieste prima di essere formattato.
Caratteri di conversione
-
i -
Il numero sarà formattato in base alle impostazioni internazionali locali (es. le impostazioni locali USA: USD 1,234.56).
-
n -
Il numero sarà formattato in base alle locali impostazioni nazionali di moneta (es. per de_DE: DM1.234,56).
-
% -
Restituisce il carattere
%.
Nota:
La categoria
LC_MONETARYdelle impostazioni locali influisce sul comportamento di questa funzione. Utilizzare setlocale() per impostare il default appropriato prima di utilizzare questa funzione.I caratteri prima e dopo la stringa di formattazione saranno restituiti immutati.
Example #1 Esempio di uso di money_format()
Per illustrare il funzionamento della funzione utilizzeremo diversi formati di impostazioni locali.
<?php
$number = 1234.56;
// stampa nel formato internazionale per l'impostazione en_US
setlocale(LC_MONETARY, 'en_US');
echo money_format('%i', $number) . "\n";
// USD 1,234.56
// Fromato italiano con 2 cifre decimali`
setlocale(LC_MONETARY, 'it_IT');
echo money_format('%.2n', $number) . "\n";
// L. 1.234,56
// Numeri negativi
$number = -1234.5672;
// Formato nazionale US, Utilizzo di () per i numeri negativi
// e 10 cifre di precisione a sinistra
setlocale(LC_MONETARY, 'en_US');
echo money_format('%(#10n', $number) . "\n";
// ($ 1,234.57)
// Simile al precente con 2 cifre di precisione a destra
// e '*' come carattere di riempimento
echo money_format('%=*(#10.2n', $number) . "\n";
// ($********1,234.57)
// Giustificazione a sinistra, con 14 posizioni di lunghezza, 8 cifre di
// precisione a sinistra, 2 di precisione a destra, senza carattere di raggruppamento
// e utilizzando l'impostazione locale de_DE.
setlocale(LC_MONETARY, 'de_DE');
echo money_format('%=*^-14#8.2i', 1234.56) . "\n";
// DEM 1234,56****
// Qualche carattere prima e dopo la specifica di formattazione
setlocale(LC_MONETARY, 'en_GB');
$fmt = 'The final value is %i (after a 10%% discount)';
echo money_format($fmt, 1234.56) . "\n";
// The final value is GBP 1,234.56 (after a 10% discount)

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.

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.

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

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;

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;
}
}
return $number;

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.

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.

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;
}
?>

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);
?>

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

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);
