Question

我花了很多时间用这个，但无法生成解决方案，所以我请求你的帮助:) 我有一个这种结构的多维PHP数组：

Array
(
    [1] => Array
    (
        [title] => Dance Type
        [id] => 2
        [children] => Array
        (
             [0] => Tango
             [1] => Salsa
             [2] => Hip-Hop
        )
    )
    [2] => Array
    (
        [title] => Age
        [id] => 3
        [children] => Array
            (
                [0] => Young
                [1] => Teen
                [2] => Senior
            )
    )
    [3] => Array
    (
        [title] => Grade
        [id] => 1
        [children] => Array
            (
                [0] => Professional
                [1] => Student
            )
    )
    [4] => Array
    (
        [title] => Groups
        [id] => 4
        [children] => Array
            (
                [0] => Small Group
                [1] => Duet
            )
    )
)

此数组可能包含无限量的键，不一定是4。

我需要的是生成以下结构的嵌套“计划”（ul / li）：

<ul>
    <li>Tango
    <ul>
        <li>Young
        <ul>
            <li>Professional
            <ul>
                <li>Small Group</li>
                <li>Duet</li>
            </ul>
            </li>
            <li>Student
            <ul>
                <li>Small Group</li>
                <li>Duet</li>
            </ul>
            </li>
        </ul>
        </li>
        <li>Teen
        <ul>

            <ul>

                <li>Duet</li>
            </ul>
            </li>

编辑：此数组直接从MySQL数据库生成（使用一个表）： eventsRegistrationRoutinesCategories表：

Answer 1

使用此..希望这有帮助

$array=//Your input array

foreach($array as $row) {
    $result[$row['title']]=$row['children'];
}


echo '<ul>';
foreach($result['Dance Type'] as $dance_type) {
    echo '<li>'.$dance_type.'</li>';
    echo '<ul>';
    foreach($result['Age'] as $age) {
        echo '<li>'.$age.'</li>';
        echo '<ul>';
        foreach($result['Grade'] as $grade) {
            echo '<li>'.$grade.'</li>';
            echo '<ul>';
            foreach($result['Groups'] as $groups) {
                echo '<li>'.$groups.'</li>';
            }
            echo '</ul>';
        }
        echo '</ul>';
    }
    echo '</ul>';
}
echo '</ul>';

Answer 2

我已经想出了这个并且会发布一个答案，以防有人需要它:) 我已经调用了我们的数组＆＃34; $ scheduleNested＆＃34;。然后我创建了一个函数：

function buildTree($array, $depth) {
    global $scheduleNested;
    echo '<ul>';
    foreach($array as $row) {
        echo '<li>';
        echo $row;
        if(isset($scheduleNested[$depth+1])) {
            buildTree($scheduleNested[$depth+1]['children'], $depth+1);
        }
        echo '</li>';
    }
    echo '</ul>';
}

然后我们在div中调用此函数：

<div class="dd" id="nestable2">
    <?
    buildTree($scheduleNested[1]['children'],1);
    ?>
</div>
