The PHP number format returns the formatted number on success otherwise it offers E_WARNING on failure when displaying a number in web pages, it’s nice to format the number in an easy-to-read way.

Syntax: number_format($number, $decimals, $decimalpoint, $separator)

Parameter Values

PHP Number Formate:- Basic number formatting

The basic range typeat|data formatting|information|info} form number_format() accepts numbers to formate, and returns a string containing the formatted range, rounded to the closest integer, with commas between every cluster of thousands:

<?php
$number = 1234567.89;
// Displays "1,234,568"
echo number_format( $number );
?>

<?php

$number = 1234567.89;

// Displays "1,234,568"

echo number_format( $number );

Important Note:
PHP number_format()function performs that it returns a string containing separator characters, therefore, we can’t use the output of PHP number format as a numeric value with different functions or maths operators.
Therefore, you do all of your calculations on the original numeric value, and also convert the value

to a string with PHP number format function, once you’re able to show it to the user.

PHP Number Formate:- Using different separators

By default, number_format() uses a comma for the thousands apparatus and a dot for the mathematical

notation. therefore, to use completely different separators, pass the new mathematical notation or decimal

point separator as the third argument, and also the new thousands separator as the fourth argument.
The given below the following example shows a number using the French convention — a space for

the thousands separator and a comma for the decimal point.

$number = 123456.784321;
// Displays "123 456,78"
echo number_format( $number, 2, ',', ' ' );

$number = 123456.784321;

// Displays "123 456,78"

echo number_format( $number, 2, ',', ' ' );

furthermore, If you wanted to displayed a number in English notation rounded to 2 decimal places, but without thousands of separators, then you can write the following program:

$number = 123456.784321;
// Displays "123456.78"
echo number_format( $number, 2, '.', '' );

$number = 123456.784321;

// Displays "123456.78"

echo number_format( $number, 2, '.', '' );

Important Note: PHP’s localeconv() function:- you can use this function to find out the computer’s current locale settings for the decimal point and thousands separator — handy for plugging into PHP number_format().

<?php
echo number_format("9999999")."<br>";
echo number_format("9999999",2)."<br>";
echo number_format("9999999",2,",",".");
?>

<?php

echo number_format("9999999")." ";

echo number_format("9999999",2)." ";

echo number_format("9999999",2,",",".");

9,999,999
9,999,999.00
9.999.999,00

9,999,999

9,999,999.00

9.999.999,00

<?php
$number=479454251;
echo number_format($number).'<br>';
echo number_format($number, 2).'<br>';
echo number_format($number, 3).'<br>';
echo number_format($number, 2, ',', '.');
?>

<?php

$number=479454251;

echo number_format($number).' ';

echo number_format($number, 2).' ';

echo number_format($number, 3).' ';

echo number_format($number, 2, ',', '.');

479,454,251
479,454,251.00
479,454,251.000
479.454.251,00

479,454,251

479,454,251.00

479,454,251.000

479.454.251,00

Program Condition: Therefore, if you want to return a price: One parameter will round the number (formatted without decimals). Two (2) parameters should give us the result which you want, let’s see the program:

<?php
$number = 2999.9;
$formated_num = number_format($number)."<br>";
echo $formated_num;
$formated_num = number_format($number, 2);
echo $formated_num;
?>

<?php

$number = 2999.9;

$formated_num = number_format($number)." ";

echo $formated_num;

$formated_num = number_format($number, 2);

echo $formated_num;

3,000
2,999.90

1 2	3,000 2,999.90
