your doing the number format before the rounding.. here's a version of
the function that should fit the bill:

function round_to_half_cent( $value )
{
        $value *= 100;
        if( $value == (int)$value || $value < ((int)$value)+0.3 ) {
                return number_format( (int)$value/100 , 2);
        } else if($value > ((int)$value)+0.6) {
                return number_format( (int)++$value/100 , 2);
        }
        return number_format( 0.005+(int)$value/100 , 3);
}


echo round_to_half_cent( 12.1 );       // 12.10
echo round_to_half_cent( 12.103 );     // 12.105
echo round_to_half_cent( 12.107 );     // 12.11
echo round_to_half_cent( 123456.789 ); // 123,456.79
