From: rob at neovidamedia dot com Operating system: Windows 7 PHP version: Irrelevant Package: *Encryption and hash functions Bug Type: Bug Bug description:Extra characters added to base64_decode() output
Description: ------------ --- >From manual page: http://www.php.net/function.base64-decode --- Run this code, and notice the output for 'Decoded' -- it looks the same as 'Original', but it is not. Select it (the result), copy it, and paste it into notepad or something, and you will see a bonus character at the end. It seems to be related to the string length of $a, and the fact that it contains a number at its end, but I could be wrong. I ran about one hundred different scenario tests, and got some funky results. PS - I am running PHP 5.2.17, but that is what my host offers. Don't think I can upgrade on my own ... Test script: --------------- $a = "Proteussing88"; function randLetter() { $int = rand(0,61); $a_z = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890"; $rand_letter = $a_z[$int]; return $rand_letter; } $pass = randLetter() . base64_encode($a) . randLetter() . randLetter() . randLetter(); $db_pass = base64_decode(substr($pass, 1, (strlen($pass) - 2))); $final = substr($db_pass, 0, (strlen($db_pass) - 1)); echo 'Original: ' . $a . '<br />Encoded: ' . $pass . '<br />Decoded: ' . $final; Expected result: ---------------- The visual result is fine, but in the background a special character is being added to the final string variable. Actual result: -------------- The final string variable looks right, but only in a browser. Paste it into notepad or any other text editor, and you get an unexpected special character at its end. -- Edit bug report at https://bugs.php.net/bug.php?id=64162&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=64162&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=64162&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=64162&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=64162&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=64162&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=64162&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=64162&r=needscript Try newer version: https://bugs.php.net/fix.php?id=64162&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=64162&r=support Expected behavior: https://bugs.php.net/fix.php?id=64162&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=64162&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=64162&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=64162&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=64162&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=64162&r=dst IIS Stability: https://bugs.php.net/fix.php?id=64162&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=64162&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=64162&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=64162&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=64162&r=mysqlcfg
