You have to use the second argument of this function round which is exactly the number of decimal places, the precision.

Example:

echo round(3.425);     // 3
echo round(3.425 , 1); // 3.4
echo round(3.425 , 2); // 3.43
echo round(3.425 , 3); // 3.425

To convert to the style of ceil but with decimal places you can do like this:

function ceil_dec($val, $dec) { 
    $pow = pow(10, $dec); 
    return ceil($pow * $val) / $pow; 
} 

echo ceil_dec(3.43, 1); // 3.5
