How should the context switch be handled when displaying text within HTML elements in PHP?

When displaying text within HTML elements in PHP, it is important to handle the context switch properly to prevent any potential security vulnerabilities, such as cross-site scripting attacks. To do this, use the htmlspecialchars() function to escape special characters in the text before outputting it to the HTML page. 

<?php
$text = "<script>alert('Hello!');</script>";
echo "<p>" . htmlspecialchars($text) . "</p>";
?>
