Why won't it decode the html object?

Question

Try it yourself:

echo(html_entity_decode("…")); 

This is echos … instead of … as it should be.

Why it will not be decoded and how can I do it?

Answer 1

Since the default target character set ISO-8859-1 does not contain the character "...". You need to explicitly specify UTF-8:

 html_entity_decode('…', ENT_QUOTES, 'UTF-8') 

Note that this has changed in PHP 5.3.3, where UTF-8 has become the default.
