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.
<?php
// Check if user is logged in
if($loggedIn) {
echo '<a href="dashboard.php">Dashboard</a>';
} else {
echo '<a href="login.php">Login</a>';
}
?>
