html实体/特殊字符解码

Question

I have a question about html decode.

I'm using WordPress' gravityforms plugin to manage forms. The formtitle includes the name of the website. This week there was a bug in the special characters, the & sign was showing in the mailbox as & . I fixed this using html specialcharacters decode which was working great. Later it appeared that there was a similar bug with the ' sign. Apparently html_specialcharacersdecode doesn't work with that one so I tried html_entities_decode as well, which also doesn't work for the ' sign.

Other signs are decoded perfectly such as < > () : -=+ so I don't really know what the problem is. I just want the ' to show as ' and not as '.

My code:

    function before_email( $email ) {
        $subject = htmlspecialchars_decode($email['subject']);
        $subject = html_entity_decode($subject);
        $email['subject'] = '$subject';
        return $email;  
    }

My concrete question is: Is there something I'm missing here? Like maybe some function similar to the ones I've tried or is there something else going wrong?

Thanks!

You can use,

$subject = html_entity_decode($subject, ENT_QUOTES);

However, I would advise against HTML encoding before you insert it into the database. Just encode it when you output it. It's better just storing the raw data in the database.
