note 69298 added to function.base64-decode

I've come across an interesting issue with an external program that submits a gzcompressed base64_encoded string to PHP via POST. The external program encodes the string using the occasional " " (space) character, however if I encode the same original string within PHP (using base64_encode), it uses a "+" (plus) character wherever the external program would use a space. On my deployed machine, running PHP 4.3.9, base64_decode is fine with the " " (space) characters, but my test server running 5.1.4 is not. It took me a while to figure out that was the issue, but I ended up fixing it with a simple: <?php $post_data = str_replace(" ","+",$_POST['string']) ?> This fix works on both the 4.3.9 and 5.1.4 machines. I am sure that the external program is probably not conforming to the standard, and it isn't a PHP problem per-se; but incase anybody else ever runs into that. ---- Server IP: 216.194.113.175 Probable Submitter: 63.116.164.218 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.base64-decode.php Edit -- https://master.php.net/note/edit/69298 Del: integrated -- https://master.php.net/note/delete/69298/integrated Del: useless -- https://master.php.net/note/delete/69298/useless Del: bad code -- https://master.php.net/note/delete/69298/bad+code Del: spam -- https://master.php.net/note/delete/69298/spam Del: non-english -- https://master.php.net/note/delete/69298/non-english Del: in docs -- https://master.php.net/note/delete/69298/in+docs Del: other reasons-- https://master.php.net/note/delete/69298 Reject -- https://master.php.net/note/reject/69298 Search -- https://master.php.net/manage/user-notes.php
