How to convert number to Indian Money format

            This Example illustrates how number can be converted to money format. Sometimes we must display number as currency and for this purpose PHP provides `money_format` function and it works in indian format fine till ten thousand ( five digit numbers )but in more than 5 digits, it fails for Indian Currency.

So, Here we will use user define function look like below.

index.php

<?php

function custom_format($n, $d = 0) {

    $n = number_format($n, $d, '.', '');

    $n = strrev($n);

    if ($d) $d++;

    $d += 3;

    if (strlen($n) > $d)

        $n = substr($n, 0, $d) . ','

           . implode(',', str_split(substr($n, $d), 2));

    return strrev($n);

}

// Call Function with number agrument

echo custom_format(1234567890);       // 1,23,45,67,890

echo custom_format(1234567890, 2);    // 1,23,45,67,890.00

echo custom_format(1234567890.11);    // 1,23,45,67,890

echo custom_format(1234567890.11, 2); // 1,23,45,67,890.11

?>

Here we create function `custom_format` with numeric  argument. That’s it we got number in Currency format.
