I'm having issues trying to base64_decode the encoded string . I tested in a lot of php and linux versions and on some got the error and on another didn't. Mostly the problem seams to be on PHP 5.X

Please provide a working reproduce code, using the code above I can see only "bool(false)".
 [2006-12-20 19:38 UTC] herbert dot fischer at gmail dot com 
Yes! "False" (and not only false) because base64_decode cannot even decode this encoded string sometimes. mb_convert_encoding did decode, but with lots of garbage. Sometimes base64_decode decoded with garbage just like mb_convert_encoding did, without returning just "false".

Decoding the encoded text with other means, works. Tested with a Perl script, http://makcoder.sourceforge.net/demo/base64.php, etc.

I don't get it. So what's the problem? base64_decode() is unable to decode broken/invalid data, that's expected.
Other means, like libmbfl (used in ext/mbstring) may try to decode it and get a garbage instead. Which is also expected.
What is the problem?

Sorry for the mess. Just found that the encoded string was loosing a single "+" during a POST (in url-encoded format).
Please, close this. Bogus.
