money_format — Formats a number as a currency string
This function has been DEPRECATED as of PHP 7.4.0, and REMOVED as of PHP 8.0.0. Relying on this function is highly discouraged.
$format, float $number): string
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.
formatThe format specification consists of the following sequence:
a % character
optional flags
optional field width
optional left precision
optional right precision
a required conversion character
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).
A decimal digit string specifying a minimum field width. Field will
be right-justified unless the flag - is used.
Default value is 0 (zero).
#nThe 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.
.pA 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 locale in use. The amount being formatted is rounded to the specified number of digits prior to formatting.
iThe number is formatted according to the locale's international currency format (e.g. for the USA locale: USD 1,234.56).
nThe number is formatted according to the locale's national currency format (e.g. for the de_DE locale: EU1.234,56).
%
Returns the % character.
numberThe number to be formatted.
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.

Example #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, without the 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');
$fmt = 'The final value is %i (after a 10%% discount)';
echo money_format($fmt, 1234.56) . "\n";
// The final value is GBP 1,234.56 (after a 10% discount)
?>
Note:
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.
Note:
The
LC_MONETARYcategory of the locale settings, affects the behavior of this function. Use setlocale() to set to the appropriate default locale before using this function.
