PHP - 从基于值名称组合类似值的 php 数组构建多级 HTML 菜单

Question

我在 SO 上搜索了一下，没能找到这个独特的用例，但也许我不知道如何表达它。我希望使用 PHP 数组(请参阅下面的格式)构建一个动态 HTML 菜单，当存在匹配项时将相同的字符串值复制到子菜单中。

这可能太复杂了，但我想知道是否可行，以及是否有人有代码示例。 我不介意更改“verse”数组值结构以使其更加可变并使其正常工作(可能将其转换为数组，因为其中有 1:many 潜在值。) p>

我无法让下面的 HTML 格式非常适合 SO，但请求的要点是所有具有匹配书籍/章节字符串的文章都将放在一起并嵌套。如果诗篇 121 有 2 个条目(在下面的数组中)，那么它们应该嵌套在同一个子菜单中。

所需的结束结构(请注意，因为 2 个字符串与诗篇第 121 章匹配，所以它们组合在一起:

Hebrews
    Chapter 12
        Verse 26-28
    Chapter 9
        Verse 23-24

Psalms
    Chapter 121
         Verse 3-4
         Verse 7-10
    Chapter 16
         Verse 11

Exodus
    Chapter 33
         Verse 14

预先感谢您的帮助!

PHP 数组:

<?php

$articles = array(

array(
    'contentid' => '109',
    'full' => 'Song by Artist (Ref 109)',
    'verse' => 'Hebrews 12:26-28'),

array(
    'contentid' => '110',
    'full' => 'Song by Artist (Ref 110)',
    'verse' => 'Psalms 121:3-4'),

array(
    'contentid' => '111',
    'full' => 'Song by Artist (Ref 111)',
    'verse' => 'Hebrews 9:23-24'),

array(
    'contentid' => '112',
    'full' => 'Song by Artist (Ref 112)',
    'verse' => 'Psalms 16:11; Exodus 33:14; Psalms 121:7-10'));

?>

我想绘制一个如下所示的 HTML 菜单:

<!-- Hebrews -->
                    <div class="submenu">
                        <a href="#">**Hebrews**</a>
                        <!-- Level 2 menu -->
                        <div>
                            <div>


                                <div class="submenu">
                                    <a href="#">Chapter *12*</a>
                                    <!-- Level 3 menu -->
                                    <div>
                                        <div>
                                            <a href="#"><span>Song by Artist (Ref 109)</span>Verse *26-28*</a>

                                    </div>
                                </div>

                                <div class="submenu">

                                    <!-- Level 3 menu -->
                                    <div>
                                        <div>
                                            <a href="#"><span>Song by Artist (Ref 111)</span>Verse *23-24*</a>
                                        </div>
                                    </div>
                                </div>

<!-- Psalms -->

                    <div class="submenu">
                        <a href="#">**Psalms**</a>
                        <!-- Level 2 menu -->
                        <div>
                            <div>

                                <div class="submenu">
                                    <a href="#">Chapter *121*</a>
                                    <!-- Level 3 menu -->
                                    <div>
                                        <div>
                                            <a href="#"><span>Song by Artist (Ref 110)</span>Verse *3-4*</a>
                                            <a href="#"><span>Song by Artist (Ref 112)</span>Verse *7-10*</a>                                       </div>
                                    </div>
                                </div>

您还可以使用 \t 添加制表符空间。我的建议是如果你已经像这样生成它。通过删除所有 \n 使其成为一行。
