如何在＆ndash;分割Wordpress标题？ 用PHP？

Question

I am working on my Wordpress blog and its required to get the title of a post and split it at the "-". Thing is, its not working, because in the source its &ndash and when I look at the result on the website, its a "long minus" (–). Copying and pasting this long minus into some editor makes it a normal minus (-). I cant split at "-" nor at &ndash, but somehow it must be possible. When I created the article, I just typed "-" (minus), but somewhere it gets converted to – automatically.

Any ideas?

Thanks!

I think I found it. I remember that I have meet the similar problem that when I paste code in my post the quote mark transform to an em-quad one when display to readers.

I found that is in /wp-include/formatting.php line 56 (wordpress ver 3.3.1), it defined some characters need to replace

$static_characters = array_merge( array('---', ' -- ', '--', ' - ', 'xn–', '...', '``', '\'\'', ' (tm)'), $cockney );
$static_replacements = array_merge( array($em_dash, ' ' . $em_dash . ' ', $en_dash, ' ' . $en_dash . ' ', 'xn--', '…', $opening_quote, $closing_quote, ' ™'), $cockneyreplace );

and in line 85 it make an replacement

// This is not a tag, nor is the texturization disabled static strings
$curl = str_replace($static_characters, $static_replacements, $curl);
