Question

我有类别表，里面包含35个类别。我希望他们在一个while循环中进入四个div。

<?php 
    $count = 0;
    $cat = pullcategories();
    $catcount = mysqli_num_rows($cat);
    $percat = ceil($catcount / 4);

    $topcats = pulltopcategories($count, $percat);
    //same with pullcategories, just LIMIT $count,$per //
    while ($topcats = mysqli_fetch_object($topcats)) {
        ?>
        <div class="col3">
            <ul class="list-unstyled list-dashed">
                <li>
                    <a href="">$topcats->title</a>
                </li>
            </ul>
        </div>
        <?php 
        $count = $count + $percat;
        $percat = $percat * 2; 
    } 
?>

                $count = 0;
                $cat = pullcategories();
                $catcount = mysqli_num_rows($cat);
                $percat = ceil($catcount / 4);

                $topcats = pulltopcategories($count, $percat);

这会将您的列表分为4个部分，您需要调用“$ topcats = pulltopcategories（$ count，$ percat）;” 4次能够通过所有数据。

我会把它改成这样的东西。假设“pulltopcategories（$ count，$ percat）”使用count作为限制，而percat作为SQL中的偏移量应该有效。

请尝试让我知道 - 我可以解决任何错误（如果有的话）（我的PHP有点生疏，我没有数据可以尝试这个）

<?php 
                $count = 0;
                $cat = pullcategories();
                $catcount = mysqli_num_rows($cat);
                $percat = ceil($catcount / 4);

                while ($count < catcount){ /* Loop until you have finished all cats */ 
                    $topcats = pulltopcategories($count, $percat);
                    echo "<div class="col3">
                        <ul class='list-unstyled list-dashed'>";

                    while ($topcats = mysqli_fetch_object($topcats)) {
                            echo "<li>
                                <a href=''>$topcats->title</a>
                            </li>"
                    }
                    echo "</ul>
                    </div>";
                    $count = $count + $percat;
               }
?>

PHP：将mysql结果分成四个div
