ID: 63738 Updated by: r...@php.net Reported by: r...@php.net Summary: unpack string behavior change -Status: Open +Status: Not a bug Type: Bug Package: Unknown/Other Function Operating System: GNU/Linux (Fedora 17) PHP Version: 5.5Git-2012-12-11 (snap) Block user comment: N Private report: N New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php Sorry, haven't read carefully UPGRADING - pack()/unpack() had the following changes, which bring it more in line with Perl's behavior: - Implemented format character "Z": NUL-padded string - "a" now does not remove trailing NUL characters on unpack() anymore - "A" will now strip all trailing ASCII whitespace on unpack() (it used to remove only trailing spaces).
