money_format

(PHP 4 >= 4.3.0, PHP 5, PHP 7)

money_format — Met un nombre au format monétaire

Avertissement

Cette fonction est OBSOLÈTE à partir de PHP 7.4.0, et a été SUPPRIMÉE à partir de PHP 8.0.0. Dépendre de cette fonction est fortement déconseillé.

Description

money_format(string $format, float $number): string

money_format() retourne une version formatée du nombre number. Cette fonction fait l'interface avec la fonction strfmon() de la bibliothèque C, à la différence près que cette implémentation ne convertit qu'un nombre à la fois.

Liste de paramètres

format

Le paramètre de format est constitué de la séquence suivante :

un caractère %
une configuration optionnelle
une taille de champ optionnelle
une précision à gauche optionnelle
une précision à droite optionnelle
un caractère de conversion obligatoire

Drapeaux

Une ou plusieurs des configurations suivantes sont utilisables :

=f: Le caractère = suivi par un octet unique f qui sera utilisé comme caractère de remplissage. Le caractère de remplissage par défaut est espace.
^: Désactive le groupage de caractères (tel que défini dans la configuration locale).
+ ou (: Spécifie le style de formatage pour les nombres positifs et négatifs. Si + est utilisé, les équivalents dans la configuration locale de + et - seront utilisés. Si ( est utilisé, les sommes négatives seront placées entre parenthèses. Si aucune spécification n'est fournie, la valeur par défaut est +.
!: Supprime le simple monétaire dans la chaîne finale.
-: Si fourni, cette configuration fait que les champs seront justifiés à gauche (complétés à droite), au contraire de la configuration par défaut qui est justifiée à droite, et complétée à gauche.

Taille du champ

w: Un nombre décimal qui spécifie la taille minimale du champ. Le champ sera complété à gauche, à moins que la configuration - ne soit utilisée. Par défaut, cette valeur est de 0.

Précision à gauche

#n

Le nombre maximal de chiffres (n) attendus à gauche du séparateur décimal (e.g. la virgule). Cette option est généralement utilisée pour conserver l'alignement de colonnes de nombres, en utilisant un caractère pour compléter le nombre si ce dernier a moins de n chiffres. Si le nombre réel de chiffres est plus grand que n, cette spécification est ignorée.

Si le groupage n'a pas été supprimé via la configuration ^, les séparateurs de groupage seront insérés avant le caractère de remplissage (le cas échéant). Les séparateurs ne seront pas appliqués aux caractères de remplissage, même si ce caractère est un nombre.

Pour s'assurer de l'alignement, tous les caractères apparaissant avant et après le nombre formaté, tels que les symboles monétaires ou les signes négatif et positif, seront placés au même endroit grâce à des espaces supplémentaires, afin que toutes les tailles des nombres soient les mêmes.

Précision à droite

.p: Un point suivi par un nombre de décimales (p). Si la valeur de p est 0 (zéro), le séparateur décimal et les décimales seront supprimés. Si aucune précision à droite n'est précisée, la valeur par défaut sera lue dans la configuration locale. Le nombre formaté sera alors arrondi pour satisfaire les contraintes d'affichage.

Caractères de conversion

i: Le nombre est formaté suivant le format monétaire international de la configuration locale (e.g. pour la France : 1 234,56 F).
n: Le nombre est formaté en fonction du format monétaire national (e.g. pour la configuration de_DE : EU1.234,56).
%: Retourne le caractère %.

number

Le nombre à formater.

Valeurs de retour

Retourne la chaîne formatée. Les caractères avant et après la chaîne formatée seront retournés, inchangés. Une valeur non-numérique pour number retourne null et émet une alerte E_WARNING.

Historique

Version	Description
7.4.0	Cette fonction est obsolète. Utiliser NumberFormatter::formatCurrency() à la place.

Exemples

Exemple #1 Exemple avec money_format()

Voici plusieurs exemples d'utilisation de la fonction money_format() avec différentes chaînes de formatage, et configurations locales.

<?php

$number = 1234.56;

// Affichons ce nombre au format international pour en_US
setlocale(LC_MONETARY, 'en_US');
echo money_format('%i', $number) . "\n";
// USD 1,234.56

// Et au format italien national avec 2 decimales
setlocale(LC_MONETARY, 'it_IT');
echo money_format('%.2n', $number) . "\n";
// L. 1.234,56

// Utilisation d'un nombre négatif
$number = -1234.5672;

// Format US national, avec les parenthèeses pour les nombres négatifs
// et 10 chiffres de précision à gauche
setlocale(LC_MONETARY, 'en_US');
echo money_format('%(#10n', $number) . "\n";
// ($        1,234.57)

// Format similaire au précédent, en ajoutant 2 décimales
// pour la précision à droite, et en utilisant le caractère de remplissage '*'
echo money_format('%=*(#10.2n', $number) . "\n";
// ($********1,234.57)

// Utilisons maintenant la justification à gauche, avec un champ de 14 caractères
// de long, sans groupage de chiffres, et en utilisant le format international
// pour de_DE
setlocale(LC_MONETARY, 'de_DE');
echo money_format('%=*^-14#8.2i', 1234.56) . "\n";
// DEM 1234,56****

// Ajoutons encore à l'exemple précédent
setlocale(LC_MONETARY, 'en_GB');
$fmt = 'La valeur finale est %i (après 10 %% de remise)';
echo money_format($fmt, 1234.56) . "\n";
// La valeur finale est GBP 1,234.56 (après 10 % de remise)

?>

Notes

Note:
La fonction money_format() est uniquement définie si le système a les capacités strfmon. Par exemple, Windows ne les a pas, donc, money_format() n'est pas définie sous Windows.

Note:
La catégorie LC_MONETARY de la configuration locale affecte le comportement de cette fonction. Utilisez setlocale() pour configurer correctement PHP avant d'utiliser cette fonction.

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.

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'    => '€',

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
number_format_drop_zero_decimals(54.007, 2) ==> 54.01
number_format_drop_zero_decimals(54.000, 2) ==> 54
number_format_drop_zero_decimals(54.00, 2) ==> 54
number_format_drop_zero_decimals(54.0, 2) ==> 54
number_format_drop_zero_decimals(54.1, 2) ==> 54.10
number_format_drop_zero_decimals(54., 2) ==> 54
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
number_format_drop_zero_decimals(54 + .00, 2) ==> 54

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;

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.

Rafael M. Salvioni's code has a small bug in it when the value is positive and the format provided contains a ( flag.  The value should only be surrounded in parenthesis when the value is negative.  This should fix it:

<?php

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;



}

?>



Thanks,

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.

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

//////////////



?>



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

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);

/**
 * Formats a number as a currency string. Rounds every decimal digit to a defined precision on its own.
 *
 * @param string $format The format for the money_format function
 * @param float|int|string $number The number to be formatted
 * @param int $maxPrecision Round up to the $maxPrecision number of decimal digit. Default is: 2
 * @param int $roundingType Rounding type for the round function. Default is: \PHP_ROUND_HALF_UP

 */
function money_format_rounded($format, $number, $maxPrecision = 2, $roundingType = \PHP_ROUND_HALF_UP)
{
    $strlen = strlen($number);
    if ($strlen === 0) {
        return money_format($format, $number);
    }

    $length = $strlen - strrpos($number, '.') - 1;
    if ($length <= 0) {
        return money_format($format, $number);
    }

    $rounded = $number;
    for ($i = --$length; $i >= $maxPrecision; $i--) {
        $rounded = round($rounded, $i, $roundingType);
    }

    return money_format($format, $rounded);
}
