What is the function for decoding HTML entities in PHP and when should it be used?

When working with HTML content in PHP, sometimes you may encounter special characters encoded as HTML entities (e.g. &lt; for <). To decode these entities and display the actual characters, you can use the htmlspecialchars_decode() function in PHP. This function converts special HTML entities back to their corresponding characters. 

// Example of decoding HTML entities in PHP
$html_content = &quot;&amp;lt;h1&amp;gt;Hello World&amp;lt;/h1&amp;gt;&quot;;
$decoded_content = htmlspecialchars_decode($html_content);
echo $decoded_content;
