How can developers ensure that PHP output is displayed as intended, without unexpected formatting issues?

To ensure that PHP output is displayed as intended without unexpected formatting issues, developers can use the `htmlspecialchars()` function to escape special characters in the output. This function converts characters like `<`, `>`, `&`, and `"` to their respective HTML entities, preventing them from being interpreted as HTML code and potentially causing formatting issues. 

&lt;?php
// Example output that needs to be displayed without formatting issues
$output = &quot;&lt;h1&gt;Welcome to our website!&lt;/h1&gt;&quot;;

// Escaping special characters in the output using htmlspecialchars()
echo htmlspecialchars($output);
?&gt;
