我在html中获得了这个导航菜单，我需要将其转换为php。我尝试使用php数组和foreach，但我坚持使用子项目。我现在无法弄清楚我该怎么做。有什么想法吗？
这就是我现在所做的。
为父项创建一个数组。
<div class="containermargins clearfix">
<nav class="hmenu"data-responsive-menu="true"data-responsive-levels="">
<div class="responsivemenu collapse-button">
<div class="container-inner">
<div class="menuitem ">
<a data-toggle="collapse"data-target=".hmenu .collapse-button + .navbar-collapse"href="#"onclick="return false;"><span></span></a>
</div>
</div>
</div>
<div class="navbar-collapse collapse">
<div class="horizontalmenu clearfix">
<div class="container-inner">
<ul class="menu nav nav-pills nav-justified">
`<?php foreach ($navItems as $item) {
echo '<li class="menuitem submenu-icon-only toplevel-item"><a class="active" href=\"$item[slug]\">$item[title]</a></li>';
} ?>`
</ul>
</div>
</div>
使用foreach并回显它们
<div class="containermargins clearfix">
<nav class="hmenu"data-responsive-menu="true"data-responsive-levels="">
<div class="responsivemenu collapse-button">
<div class="container-inner">
<div class="menuitem ">
<a data-toggle="collapse"data-target=".hmenu .collapse-button + .navbar-collapse"href="#"onclick="return false;"><span></span></a>
</div>
</div>
</div>
<div class="navbar-collapse collapse">
<div class="horizontalmenu clearfix">
<div class="container-inner">

这是我的html导航菜单。
<textarea class='err' rows='1' cols='29' placeholder='Enter error message...' onfocus='this.rows=5; this.cols=40;' onblur='this.rows=1; this.cols=29;var text = document.createElement("textarea"); text.attributes = this.attributes; text.value = this.value; text.onblur = this.onblur; text.onfocus = this.onfocus; this.replaceWith(text)'></textarea>

您可以使用子项创建嵌套数组，并使用recursive function进行迭代。
这样，您可以根据需要添加任意数量的子级别。
$navItems = array(
array(
"slug" => "index.php",
"title" => "Home"
),
array(
"slug" => "cruise-partners.php",
"title" => "Cruise Partners",
"subitems" => array(
array(
"slug"=>"x.html",
"title"=>"sub-item.html"
)
)
),
array(
"slug" => "destinations.php",
"title" => "Destinations"
),
array(
"slug" => "cruise-deals.php",
"title" => "Cruise Deals"
),
array(
"slug" => "cruise-type.php",
"title" => "Cruise Type",
),
array(
"slug" => "river-cruise.php",
"title" => "River Cruise"
),
array(
"slug" => "luxury.php",
"title" => "Luxury"
),
array(
"slug" => "contact.php",
"title" => "Contacts"
)
);
function drawMenu($items){
echo "<ul>";
foreach($items as $item){
echo "<li><a href='".$item['slug']."'>".$item['title']."</a>";
if(isset($item['subitems'])){
echo "<ul>";
drawMenu($item['subitems']);
echo "</ul>";
}
echo "</li>";
}
echo "</ul>";
}
drawMenu($navItems);

您需要重新构建数组以包含子项。您可以在嵌套时使用我喜欢的Short Array Syntax。
$navItems =
[
[
'title' => 'First Option'
'slug' => 'first-option'
'sub' => [
'title' => 'First Option Sub'
'slug' => 'first-option-sub'
],
[
'title' => 'First Option Sub 2'
'slug' => 'first-option-sub-2'
]
],
[
'title' => 'First Option'
'slug' => 'first-option'
'sub' => [
'title' => 'First Option Sub'
'slug' => 'first-option-sub'
]
]
]
当涉及到实际显示子项时，您需要遍历$navItem数组并检查是否存在'sub'。如果它存在，只需以相同的方式循环它。
我发现很难理解你的HTML，所以这可能不是完全相同的结构，但它应该给你这个想法。
<?php foreach ($navItems as $item) { ?>
<li class="menuitem submenu-icon-only toplevel-item">
<a class="active" href="/<?= $item['slug'] ?>">
<?= $item['title'] ?>
</a>
</li>
<?php if (isset($item['sub']) { ?>
<?php foreach($item['sub'] as $subItem) { ?>
<li class="sub-item>
<a href="/<? $subItem['slug'] ?>">
<?= $subItem['title'] ?>
</a>
</li>
<?php } ?>
<?php } ?>
<?php } ?>
