How can a link be displayed in PHP, especially in the context of a login page?

To display a link in PHP, especially in the context of a login page, you can use the anchor tag `<a>` along with the `href` attribute to specify the URL the link will navigate to. You can also use PHP to dynamically generate the URL or link text based on certain conditions, such as whether a user is logged in or not.

&lt;?php
// Check if user is logged in
if($loggedIn) {
    echo &#039;&lt;a href=&quot;dashboard.php&quot;&gt;Dashboard&lt;/a&gt;&#039;;
} else {
    echo &#039;&lt;a href=&quot;login.php&quot;&gt;Login&lt;/a&gt;&#039;;
}
?&gt;
