I wanted to use this function today and I found the documentation, especially about the flags, not particularly helpful.
Running the code below, for example, failed because the flag I used was the wrong one...
$string = 'Donna's Bakery';
$title = html_entity_decode($string, ENT_HTML401, 'UTF-8');
echo $title;
The correct flag to use in this case is ENT_QUOTES.
My understanding of the flag to use is the one that would correspond to the expected, converted outcome. So, ENT_QUOTES for a character that would be a single or double quote when converted... and so on.
Please help make the documentation a bit clearer.
