Hi Readers,
Welcome to FindNerd, today we are going to discuss how to use a number_format() function in PHP ?

Basically, a number_format() function is used to format numbers with grouped thousands. This function is very easy to implement.

Number_format() function only supports one, two, or four parameters (does not accept three arguments).

Syntax of number_format() function

number_format(number, decimal_values, decimal_point, thousand_separator)

let explain one by one

number : This is a required parameter and this is the number which has to be formatted.This is formatted with comma (,).

decimal_values :This is an optional parameter and specifies the number of decimal values after decimal_point.This is formatted with comma (.).

decimal_point :This is a optional parameter and specifies the string used as decimal point separator.

thousand_separator : This is a optional parameter and specifies the string used as thousand separator.

You can see below examples:

1.

<?php
   //define a variable of number
   $number = 256321.25;
   echo number_format($number);
?>

Output : 256,321

Because, here print only number value, So, number_format() remove all numbers which will come after decimal and just print value before decimal.

2.

<?php
   //define a variable of number
   $number = 256321.2525;
   echo number_format( $number, 2);
?>

Output :256,321.25
Because, here we are printing number value and decimal value which length is 2,
So,number_format() remove the all number which will come after 2 number decimal point.

3.

<?php
    //define a variable of number
    $number = 256321.2525;
    echo number_format( $number, 2, '/', '-');
  ?>

Output : 256-321/25

Because, here we are printing number value with arguments.
