Show a number to two decimal places

What's the right method to round a PHP string to two decimal points?

$number = "520"; // It's a string from a database



$formatted_number = round_to_2dp($number);



echo $formatted_number;

The output ought to be 520.00;

How might the round_to_2dp() function definition be?

You can use number_format():



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

Example:



$foo = "105";

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

Use round() (use if you are expecting a number in float format only, else use number_format()



echo round(520.34345, 2);   // 520.34

echo round(520.3, 2);       // 520.3

echo round(520, 2);         // 520
