试试这个，它适用于偶数和奇数标记。

$total_marks = 42;
if(($total_marks%2) == 0)
{
    $num1 = $total_marks/2;
    $num2 = $num1;
    echo $num1 ." AND ".$num2." sum is ".$total_marks ;
}else
{
    $num1 = $total_marks/2; 
    $num1 = floor($num1);
    $num2 = $num1  + 1;

    echo $num1 ." AND ".$num2." sum is ".$total_marks ;
}
