formatting - PHP: show a number to 2 decimal places -


what's correct way round php string 2 decimal places?

$number = "520"; // it's string db  $formatted_number = round_to_2dp($number);  echo $formatted_number;

output "520.00";

how function round_to_2dp() definition should be?

you can use number_format():

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

example:

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

this function returns string.
