How does HTML entities decoding (html_entity_decode) play a role in preserving database outputs in PHP applications?

HTML entities decoding (html_entity_decode) is important in PHP applications to ensure that special characters are properly displayed in database outputs. When data is stored in a database, special characters are often encoded as HTML entities to prevent code injection attacks. By using html_entity_decode, these entities are converted back to their original characters, preserving the integrity of the data when it is displayed on a webpage.

// Example of using html_entity_decode to decode HTML entities in a database output
$encoded_data = "<p>This is an example & text with HTML entities</p>";
$decoded_data = html_entity_decode($encoded_data);
echo $decoded_data;
