Question

我通过自举建立了一个网站，现在我正试图使其更具活力。我要完成的过程不是使用引导程序。我真的很想念这件事吗？请您看看我的代码吗？

（我不想用代码重载这篇文章，所以只显示nav.php和array.php）我已经将nav.php包含在<nav></nav>和array.php中的头文件中。非常高。

任何帮助将不胜感激-我才刚刚开始自己的旅程，所以请像我不太懂的那样对我轻描淡写，因为这是真的，我不是！：-）

//nav.php which I took out of the header
<a class="navbar-brand" href="index.html">Harrisons      Hair &amp; Beauty</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse justify-content-end" id="navbarNav">
<ul class="navbar-nav">

    <?php 

        foreach($navItems as $item){
            echo "<li class=\"nav-item\">
                  <a class=\"nav-link\"  href=\"$item[slug]\">$item[title]</a>
                  </li>";
        }

Answer 1

要在echo语句中串联字符串，可以使用

import asyncio import websockets conn = websockets.connect('ws://127.0.0.1:8000/ws/registration/123') conn.send('hello') 或
echo "..." . $item['slug'] . "..."。

还要确保echo "... {$item['slug']} ..."数组的声明在$navItems输出语句之前。

祝你好运。

Answer 2

您的数组格式错误。将“”中的键包装起来，并在“ index.php”后面添加一个逗号。同样，将foreach($navItems as $item){更改为foreach($navItems as $key => $item){，以获取嵌套的数组值（导航项）。

通过这些调整，您的代码可以正常工作。
