Php: show number with two decimal point

## make number format upto 2 decimal point
here we can use, number_format():

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

## Example:

$foo = "105";
echo number_format((float)$foo, 2, '.', ''); 
// Outputs => 105.00

This function returns a string.

## also we can do using this:

$padded = sprintf('%0.2f', $unpadded); 
// 520 -> 520.00
