PHP retains two decimal places and does not round

$num = 123213.666666;echo sprintf ("%.2f", substr (sprintf ("%.3f", $num), 0,-2));

php into a method to take the whole

echo ceil (4.3);    5echo ceil (9.999);  10

php House de method, take integer

echo floor (4.3);   4echo floor (9.999); 9

Echo round (123213.666666,2);
Echo Number_format ((ceil (123213.666666 * 100))/100,2, '. ', ');
SUBSTR efficiency is poor. Wouldn't it be easier to do that?
It is recommended to read more manuals.
