Bug #76688 [NEW]: Cookie $options should not allow further arguments

From: cmb Operating system: * PHP version: 7.3Git-2018-07-31 (Git) Package: Network related Bug Type: Bug Bug description:Cookie $options should not allow further arguments Description: ------------ The support for SameSite cookie directives[1] introduced $option parameters for setcookie(), setrawcookie() and session_set_cookie_params(), but these appear to allow further arguments to be passed, which does not appear to conform to the respective RFC[2], and is generally confusing. [1] <https://github.com/php/php-src/pull/3398> [2] <https://wiki.php.net/rfc/same-site-cookie#proposal> Test script: --------------- <?php session_set_cookie_params(array('path'=>'/foo/'), 'bar', 'www.example.com'); var_dump(session_get_cookie_params()); Expected result: ---------------- A warning regarding excess arguments, which should be ignored for further processing. Actual result: -------------- array(6) { ["lifetime"]=> int(0) ["path"]=> string(5) "/foo/" ["domain"]=> string(15) "www.example.com" ["secure"]=> bool(false) ["httponly"]=> bool(false) ["samesite"]=> string(0) "" } -- Edit bug report at https://bugs.php.net/bug.php?id=76688&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=76688&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=76688&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=76688&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=76688&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=76688&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=76688&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=76688&r=needscript Try newer version: https://bugs.php.net/fix.php?id=76688&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=76688&r=support Expected behavior: https://bugs.php.net/fix.php?id=76688&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=76688&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=76688&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=76688&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=76688&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=76688&r=dst IIS Stability: https://bugs.php.net/fix.php?id=76688&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=76688&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=76688&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=76688&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=76688&r=mysqlcfg
