  • So you want to round `30.69` to `30.70`? There's no built in function that I'm aware of, but should be quite simple. – Qirel Jan 28 '19 at 06:41

If I understand your desired output correctly, that you only want to round the second decimal point, you can round with 1 decimal presicion, then use numer_format() to ensure you get the correct number of decimals. 

$num = 30.61;
echo number_format(round($num, 1), 2);

you can do this 

 $num = 3.61;
 /*round to nearest decimal place*/
 $test_number = round($num,1);
 /* ans :3.6
 format to 2 decimal place*/
 $test_number = sprintf ("%.2f", $test_number);
 /* ans : 3.60 */
