Question

此代码将显示从1991年到2100年的闰年和非闰年，我试图在闰年和其他非闰年制作表格，但我失败了。

如何以表格格式或网格系统提供？这是为了学术研究。

        function isLeap($year) {
        return ((($year % 4) == 0) && ((($year % 100) != 0)));
        }

            for($year=1991; $year<=2100; $year++)  
            {  
                If (isLeap($year))  
                {   
                    $leap="$year : LEAP YEAR <br/>";
                    //echo "<div class='col-sm-12'>" . $leap . "</div>";
                    echo $leap;
                }  
                else  
                {  
                    $nonLeap="$year : Not leap year <br/>";  
                    //echo "<div class='col-sm-6'>" . $nonLeap ."</div>";       
                    echo $nonLeap;

Answer 1

您的isLeap功能有误。您也可以参考此post。

function isLeap($year) {
    return ((($year % 4) == 0) && ((($year % 100) != 0) || (($year % 400) == 0)));
}

for($year=1991; $year<=2100; $year++)  
{  
    if (isLeap($year))  
    {   
        $leaps[] = $year;
    }  
    else  
    {  
        $nonLeaps[] = $year;
    }
}

echo '<table><tr>';
foreach($leaps as $y)
{
  echo '<td>' . $y . '</td>';
}
echo '</tr></table>';
