PHP round half up doesn't work

Question

I have this code

I want to round two decimals to half up, I expect a value as 0.58... but

Answer 1

function round_up($value, $places)
{
  $mult = pow(10, abs($places));
  return $places < 0 ?
  ceil($value / $mult) * $mult :
  ceil($value * $mult) / $mult;
}

echo round_up(0.572,2);

Hope this will work for you!!
