PHP number rounding

[johnsmith153]

I need a formula for rounding a number to 2 decimal places, but the last number must be a 5 or 0 (i.e. 1 dp if it is 0)

 

 

so:

 

1.4798 = 1.5

5.4567 = 5.45

1.2356 = 1.25

1.2011 = 1.2

1.1945 = 1.2

function roundTo($number, $to){
    return number_format(round($number/$to, 0)* $to, 2);
}

echo roundTo($number,.05);
