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 — 数値を金額文字列にフォーマットする
警告
この関数は PHP 7.4.0 で 非推奨 になり、PHP 8.0.0 で 削除 されました。この関数に頼らないことを強く推奨します。
説明
money_format() は、number
をフォーマットして返します。この関数は C のライブラリ関数
strfmon() をラップしたものですが、一度に
変換できる数値がひとつだけであるという点が異なります。
パラメータ
-
format -
フォーマット指定の書式は以下の順になります。
%文字フラグ(オプション)
フィールドの幅(オプション)
左精度(オプション)
右精度(オプション)
変換文字(必須)
フラグ
以下のフラグのうちひとつあるいは複数が使用可能です。
-
=f -
文字
=の後に続く(シングルバイトの)文字 f が、数値埋め文字として使用されます。 デフォルトはスペース文字です。 -
^ -
グループ化文字(現在のロケールで定義されている)を使用しないようにします。
-
+あるいは( -
正の数、負の数の書式を指定します。
+が使用された場合、+および-に該当する そのロケールの符号マークが使用されます。(が使用された場合、負の数は括弧で囲まれます。何も指定しなかった場合、 デフォルトは+です。 -
! -
出力文字列から通貨記号を除きます。
-
- -
指定した場合、すべてのフィールドを左詰め(右側に数値埋め文字が追加される) にします。デフォルトはこれと反対で、すべてのフィールドを右詰め (左側に数値埋め文字が追加される)にします。
フィールドの幅
- w
-
10 進の数値形式の文字列で、フィールドの幅の最小値を指定します。フラグ
-が使用されていない限り、フィールドは 右詰めとなります。デフォルト値は 0(ゼロ) です。
左精度
-
#n -
10 進の基準文字(例: 小数点)より左側の最大の桁数 (n) を指定します。これは通常、 n より少ない桁数の数値に対して 数値埋め文字を使用することで、出力の桁位置をそろえるために 使用されます。実際の桁数が n より 大きい場合、この設定は無視されます。
^フラグでグループ化文字が抑止されていない場合、 (もし存在するなら)数値埋め文字が追加される前にグループ化文字が 挿入されます。グループ化文字は数値埋め文字には適用されません。 たとえ数値埋め文字が数字であったとしても同様です。位置あわせを確実にするため、出力中の数値の前後に表れる文字(たとえば 通貨記号や符号など)は、必要に応じて(正の数と負の数の長さをそろえるなど の理由で)スペース文字が付加されることがあります。
右精度
-
.p -
ピリオドに続く数値(p) で、10 進の基準文字以降の桁数を指定します。 p の値が 0(ゼロ)であった場合、基準文字と それ以降の数値は省略されます。右精度が指定されていない場合、 使用中の現在のロケールからデフォルト値を検出します。 フォーマットされる数値は、フォーマット前にこの桁数に丸められます。
変換文字
-
i -
ロケールの国際通貨フォーマット(例: USA ロケールでは USD 1,234.56)によってフォーマットします。
-
n -
ロケールの国内通貨フォーマット(例: de_DE ロケールでは EU1.234,56) によってフォーマットします。
-
% -
%文字を返します。
-
number -
フォーマットする数値。
戻り値
フォーマットした文字列を返します。
フォーマット文字列の前後の文字は、そのまま返されます。
number が非数値の場合は null を返し、
E_WARNING を発行します。
例
例1 money_format() の例
この関数の使用法を詳しく説明するために、 さまざまなロケールおよびフォーマット指定を使用します。
<?php
$number = 1234.56;
// en_US ロケールの国際フォーマットで表示します
setlocale(LC_MONETARY, 'en_US');
echo money_format('%i', $number) . "\n";
// USD 1,234.56
// イタリアの国内フォーマットで小数点以下 2 桁で表示します
setlocale(LC_MONETARY, 'it_IT');
echo money_format('%.2n', $number) . "\n";
// Eu 1.234,56
// 負の数を使用します
$number = -1234.5672;
// US の国際フォーマットで、負の数には () を使用して
// 左精度を 10 桁にします
setlocale(LC_MONETARY, 'en_US');
echo money_format('%(#10n', $number) . "\n";
// ($ 1,234.57)
// 上と同じですが、それに加えて右精度を 2 桁
// 数値埋め文字として '*' を使用します
echo money_format('%=*(#10.2n', $number) . "\n";
// ($********1,234.57)
// 左詰め、幅 14 桁、左精度 8 桁、右精度 2 桁、グループ化文字なしで
// de_DE ロケールの国際フォーマットを使用します。
setlocale(LC_MONETARY, 'de_DE');
echo money_format('%=*^-14#8.2i', 1234.56) . "\n";
// Eu 1234,56****
// 変換指定の前後に宣伝文句を追加します
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)
?>注意
注意:
システムで strfmon が使用可能な場合のみ money_format() 関数が定義されます。例えば、Windows では strfmon は使用できません。 そのため money_format() は Windows では 定義されていません。
注意:
ロケール設定のうち、
LC_MONETARYカテゴリの内容が この関数の振る舞いに影響します。この関数を使用する前に、 setlocale() で適切なデフォルトロケールを 設定してください。
参考
- setlocale() - ロケール情報を設定する

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.

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:

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)

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

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);
