Create custom money format function in php with allow two digit only

Here is an example of a function in PHP that you can use to format a monetary value with two decimal places:

function format_money($value) {
  // Use number_format() to add commas as thousands separators and round to two decimal places
  $formatted = number_format($value, 2);

  // Use preg_replace() to remove any extra decimal places beyond the two that were added by number_format()
  $formatted = preg_replace('/\.00$/', '', $formatted);

  // Return the formatted value
  return $formatted;
}

You can use this function by calling it with a monetary value as an argument, like this:

$value = 123456.789;
echo format_money($value); // Outputs: 123,456.79

The function first uses the number_format() function to add commas as thousands separators and round the value to two decimal places. It then uses the preg_replace() function to remove any extra decimal places beyond the two that were added by number_format(). Finally, it returns the formatted value.
