Answer 1

创建一个迭代变量，在循环内的每个步骤中增加该变量并检查% 6 == 1。如果是这样，请开始新行。

$i = 1;

echo '<table>';
while (...) {
    echo $i % 6 == 1 ? '<tr>' : ''; // 1st, 7th, 13th loop, create new table row

    // rest of your code
    $i++;
}
echo '</table>';

                                            while($row1 = $result1->fetch_assoc())
                        {               
                               $subid=$row1['subcat_id'];
                               $sname=$row1['subcat_name'];
                               $image=$row1['image'];

                            if( $i % 6 == 0) {          
                            echo "<table><tr><td>";
