2. “

Somehow these are differ

Answer 1

Why not just use str_replace ?

$new_str = str_replace(array('’', '“'), '', $str);

Of course, this requires your PHP scripts to be saved as UTF-8.

And if this doesn't work because those characters cannot be properly written using UTF-8, you'll have to fallback to using their hexadecimal representations.

For example :

$new_str = str_replace(array('\xC2\x91', '\xC2\x93'), '', $str);

(Not sure the hexadecimal values I used are really those of your two special quotes, though)
