Question

I’m having some trouble decoding & to & within a mail function:

This is the code:

$betreff = $_REQUEST["Betreff"];
$betreffUTF8 = "=?UTF-8?B?".base64_encode($betreff)."?=";     
$betreffFinal = str_replace('$amp;', '&', $betreffUTF8);

I’m pretty sure it should work like that, but for some reason it doesn’t.

Any idea?

Update:
Yes, the $amp; was just a typo.

You won’t find any & inside a base64_encode()ed string 🙂

$betreff = $_REQUEST["Betreff"];
$betreffClean = str_replace('&', '&', $betreff);
$betreffUTF8 = "=?UTF-8?B?".base64_encode($betreffClean)."?=";     

I’ve reversed the operation by first replacing the &amp and then applying base64_encode().
