What is the recommended method for outputting HTML special characters in PHP to ensure proper display in the browser?

When outputting HTML special characters in PHP, it is important to properly escape them to ensure they are displayed correctly in the browser. This can be done using the htmlspecialchars() function in PHP, which converts special characters to their corresponding HTML entities. By using this function, you can prevent potential security vulnerabilities such as cross-site scripting attacks. 

<?php
$string = "<h1>Hello, world!</h1>";
echo htmlspecialchars($string);
?>
