What is the function `html_entity_decode()` used for in PHP?

The `html_entity_decode()` function in PHP is used to convert HTML entities back to their corresponding characters. This is useful when you have HTML-encoded text that you want to display as plain text on a webpage. For example, if you have text with entities like `&lt;`, `&gt;`, or `&amp;`, `html_entity_decode()` will convert them back to `<`, `>`, and `&` respectively.

$decoded_text = html_entity_decode($html_encoded_text);
echo $decoded_text;
// Output: &lt;p&gt;Hello, &amp;world&amp; &lt;/p&gt;
