money_format

(PHP 4 >= 4.3.0, PHP 5)

money_formatFormats a number as a currency string

Opis

string money_format ( string $format , float $number )

money_format() returns a formatted version of number. This function wraps the C library function strfmon(), with the difference that this implementation converts only one number at a time.

Parametry

format

The format specification consists of the following sequence:

  • a % character

  • optional flags

  • optional field width

  • optional left precision

  • optional right precision

  • a required conversion character

Flags

One or more of the optional flags below can be used:

=f

The character = followed by a (single byte) character f to be used as the numeric fill character. The default fill character is space.

^

Disable the use of grouping characters (as defined by the current locale).

+ or (

Specify the formatting style for positive and negative numbers. If + is used, the locale's equivalent for + and - will be used. If ( is used, negative amounts are enclosed in parenthesis. If no specification is given, the default is +.

!

Suppress the currency symbol from the output string.

-

If present, it will make all fields left-justified (padded to the right), as opposed to the default which is for the fields to be right-justified (padded to the left).

Field width

w

A decimal digit string specifying a minimum field width. Field will be right-justified unless the flag - is used. Default value is 0 (zero).

Left precision

#n

The maximum number of digits (n) expected to the left of the decimal character (e.g. the decimal point). It is used usually to keep formatted output aligned in the same columns, using the fill character if the number of digits is less than n. If the number of actual digits is bigger than n, then this specification is ignored.

If grouping has not been suppressed using the ^ flag, grouping separators will be inserted before the fill characters (if any) are added. Grouping separators will not be applied to fill characters, even if the fill character is a digit.

To ensure alignment, any characters appearing before or after the number in the formatted output such as currency or sign symbols are padded as necessary with space characters to make their positive and negative formats an equal length.

Right precision

.p

A period followed by the number of digits (p) after the decimal character. If the value of p is 0 (zero), the decimal character and the digits to its right will be omitted. If no right precision is included, the default will dictated by the current local in use. The amount being formatted is rounded to the specified number of digits prior to formatting.

Conversion characters

i

The number is formatted according to the locale's international currency format (e.g. for the USA locale: USD 1,234.56).

n

The number is formatted according to the locale's national currency format (e.g. for the de_DE locale: EU1.234,56).

%

Returns the % character.

number

The number to be formatted.

Zwracane wartości

Returns the formatted string. Characters before and after the formatting string will be returned unchanged. Non-numeric number causes returning NULL and emitting E_WARNING.

Notatki

Informacja:

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.

Informacja:

The LC_MONETARY category of the locale settings, affects the behavior of this function. Use setlocale() to set to the appropriate default locale before using this function.

Przykłady

Przykład #1 money_format() Example

We will use different locales and format specifications to illustrate the use of this function.

<?php

$number 
1234.56;

// let's print the international format for the en_US locale
setlocale(LC_MONETARY'en_US');
echo 
money_format('%i'$number) . "\n";
// USD 1,234.56

// Italian national format with 2 decimals`
setlocale(LC_MONETARY'it_IT');
echo 
money_format('%.2n'$number) . "\n";
// Eu 1.234,56

// Using a negative number
$number = -1234.5672;

// US national format, using () for negative numbers
// and 10 digits for left precision
setlocale(LC_MONETARY'en_US');
echo 
money_format('%(#10n'$number) . "\n";
// ($        1,234.57)

// Similar format as above, adding the use of 2 digits of right
// precision and '*' as a fill character
echo money_format('%=*(#10.2n'$number) . "\n";
// ($********1,234.57)

// Let's justify to the left, with 14 positions of width, 8 digits of
// left precision, 2 of right precision, withouth grouping character
// and using the international format for the de_DE locale.
setlocale(LC_MONETARY'de_DE');
echo 
money_format('%=*^-14#8.2i'1234.56) . "\n";
// Eu 1234,56****

// Let's add some blurb before and after the conversion specification
setlocale(LC_MONETARY'en_GB');
$fmt 'The final value is %i (after a 10%% discount)';
echo 
money_format($fmt1234.56) . "\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.

<?

       $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,

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, 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
number_format_drop_zero_decimals(54.0007, 4) ==> 54.0007

This is a some function posted before, however various bugs were corrected.

Thank you to Stuart Roe by reporting the bug on printing signals.

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.

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.

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

<?php
echo formatMoney(1050); # 1,050
echo formatMoney(1321435.4, true); # 1,321,435.40
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;
}

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;

}
?>

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'); ?>

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.

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);
?>
