How can PHP developers convert HTML entities like "& # 2 1 4 ;" back to their original characters like "Ö" in a database context?

When storing HTML entities like "& # 2 1 4 ;" in a database, PHP developers can use the html_entity_decode function to convert them back to their original characters like "Ö". This function decodes all HTML entities in a string. By retrieving the stored HTML entities from the database and applying html_entity_decode, developers can display the original characters on their web pages. 

// Retrieve HTML entities from the database
$htmlEntities = "& # 2 1 4 ;";

// Decode HTML entities to original characters
$decodedString = html_entity_decode($htmlEntities);

// Display the original characters
echo $decodedString;
