What are the potential pitfalls of using <ul> and [*] tags for displaying categories in PHP?

Using <ul> and <li> tags for displaying categories in PHP can lead to accessibility issues for users who rely on screen readers or keyboard navigation. To solve this problem, it's recommended to use semantic HTML elements like <nav> and <ul> with proper ARIA attributes to enhance accessibility.

&lt;nav&gt;
    &lt;ul&gt;
        &lt;?php foreach($categories as $category): ?&gt;
            &lt;li&gt;&lt;a href=&quot;&lt;?php echo $category[&#039;url&#039;]; ?&gt;&quot;&gt;&lt;?php echo $category[&#039;name&#039;]; ?&gt;&lt;/a&gt;&lt;/li&gt;
        &lt;?php endforeach; ?&gt;
    &lt;/ul&gt;
&lt;/nav&gt;
