leap年和非跨越一年进入单独的桌子

此代码将显示从1991年到2100年的leap年和非leap年，我试图将table One换成leap年，而在非leap年中，我尝试了一个table年，但我失败了。

如何以表格格式或网格系统中将其带入？这是用于学术研究。

        function isLeap($year) {
        return ((($year % 4) == 0) && ((($year % 100) != 0)));
        }
            for($year=1991; $year<=2100; $year++)  
            {  
                If (isLeap($year))  
                {

                    //echo "<div class='col-sm-12'>" . $leap . "</div>";
                    echo $leap;
                }

                    //echo "<div class='col-sm-6'>" . $nonLeap ."</div>";       
                    echo $nonLeap;

您的isleap函数是错误的。您也可以参考此帖子。

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>';

感谢您的帮助，我明白了。这是答案：
