PHP format number to money format. Decimal before last 2 digits

Question

I need to format this to money format but not sure how. Can someone help

 <?php
 $input = "40025";
 echo $input;

I need to output 400.25

Answer 1

You could do this for example:

$input = 40025;
$output = $input/100;

$output = number_format($output, 2);

echo $output; // 400,25

Answer 2

As an alternative to number_format, you could also try money_format and specify a decimal before last two digits. USD example:

$input = "40025";
setlocale(LC_MONETARY, 'en_US.UTF-8');

echo money_format('%.2n', $input);

Answer 3

You can format it with sprintf

printf("%.2f" 40025/100);
