用于动态菜单css的foreach php

我在下面展示了一个css menu.php，它具有不同级别的ulli，在我进行include时调用它。

这是您的代码：

<div class="cont_menu">
        <div class="menu">

        <ul>
        <li><a class="hide" href="#" style="font-weight:bold;">CATALOGO</a>

在这里，我向您展示了结果的var_转储

   array
    'menu_descr' => string 'CATALOGO' (length=8)
    0 => string 'CATALOGO' (length=8)

    'level' => string '1' (length=1)
    2 => string '1' (length=1)
    'menu_link' => string '#' (length=1)
    3 => string '#' (length=1)

    'menu_title' => string 'Produtos sem Categoria' (length=22)
    4 => string 'Produtos sem Categoria' (length=22)

现在的问题是，我想在foreach php中集成ul和li的结果数组，考虑到它的标题在第一位，即级别1，以及它的子类别，我不知道如何在逻辑编程中表示它

谢谢大家。

这可能需要一些调整，因为我目前没有可用的PHP服务器。我希望它至少接近你所需要的

<?php
$lastLevel = 0;

foreach($t as $entry)
{
    if($entry['level'] > $lastLevel)
    {
        $lastLevel = $entry['level'];
        echo "<ul>";
    }
    else if($entry['level'] < $lastLevel)
    {
        $lastLevel = $entry['level'];
        echo "</li></ul>";
    }
    else
    {
        echo "</li>";
    }

    echo "<li><a href='" . $entry['menu_link'] . "'>" . $entry['menu_title'] . "</a>";
}

for($x = $lastLevel; $x > 0; $x--)
{
    echo "</li></ul>";
}
?>

不知道为什么这个询问者会被否决。。。这似乎是一个明确而有效的问题。

<?php
$lastLevel = 0;

foreach($t as $entry)
{
    if($entry['level'] > $lastLevel)
    {
        $lastLevel = $entry['level'];
        echo "<ul>";
    }
    else if($entry['level'] < $lastLevel)
    {
        $lastLevel = $entry['level'];
        echo "</li></ul>";
    }
    else
    {
        echo "</li>";
    }

    echo "<li><a href='" . $entry['menu_link'] . "'>" . $entry['menu_title'] . "</a>";
}

for($x = $lastLevel; $x > 0; $x--)
{
    echo "</li></ul>";
}
?>
