How can PHP developers ensure that special characters are displayed correctly in their templates?

Special characters in PHP templates can be displayed correctly by using the htmlspecialchars() function to encode the special characters before outputting them in the template. This function converts special characters like <, >, ", ', and & into their corresponding HTML entities, preventing them from being interpreted as HTML code and ensuring they are displayed correctly on the webpage. 

&lt;?php
$special_text = &quot;&lt;h1&gt;Welcome to PHP!&lt;/h1&gt;&quot;;
echo htmlspecialchars($special_text);
?&gt;
