How can HTML encoding in database entries, such as <p>, be managed effectively for display in HTML and further data processing?

When storing HTML content in a database, special characters like < and > need to be encoded to prevent code injection and ensure proper display. To manage HTML encoding effectively, you can use PHP functions like htmlentities() to encode the content before saving it to the database and then decode it using html_entity_decode() when displaying or processing the data. 

// Encode HTML content before saving to the database
$htmlContent = &quot;&lt;p&gt;This is a &lt;strong&gt;sample&lt;/strong&gt; paragraph.&lt;/p&gt;&quot;;
$encodedContent = htmlentities($htmlContent);

// Save $encodedContent to the database

// Decode HTML content when displaying or processing
$storedContent = &quot;&lt;p&gt;This is a &amp;lt;strong&amp;gt;sample&amp;lt;/strong&amp;gt; paragraph.&lt;/p&gt;&quot;;
$decodedContent = html_entity_decode($storedContent);

echo $decodedContent;
