Bug #77612 [NEW]: setcookie() sets incorrect SameSite header if all of its options filled

From: yura3d at tut dot by Operating system: Debian 9.7/Kernel 4.9.0 PHP version: 7.3.2 Package: HTTP related Bug Type: Bug Bug description:setcookie() sets incorrect SameSite header if all of its options filled Description: ------------ If I call setcookie(string $name, string $value, array $options) with all of options passed (expires, path, domain, secure, httponly, samesite), PHP generates incorrect Set-Cookie HTTP header: SameSite parameter is empty if I set "Lax", or "Str" if I set "Strict". But if I miss, for example, one option for setcookie (let it be "path"), everything is fine. This behavior doesn't depend on cookie value length. Test script: --------------- setcookie('key', 'value', [ 'expires' => time() + 31536000, 'path' => '/', 'domain' => 'example.com', 'secure' => true, 'httponly' => true, 'samesite' => 'Lax' ]); // Expected: // Set-Cookie: key=value; expires=Thu, 13-Feb-2020 12:06:47 GMT; Max-Age=31536000; path=/; domain=example.com; secure; HttpOnly; SameSite=Lax // Actual: // Set-Cookie: key=value; expires=Thu, 13-Feb-2020 12:06:47 GMT; Max-Age=31536000; path=/; domain=example.com; secure; HttpOnly; SameSite= -- Edit bug report at https://bugs.php.net/bug.php?id=77612&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=77612&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=77612&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=77612&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=77612&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=77612&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=77612&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=77612&r=needscript Try newer version: https://bugs.php.net/fix.php?id=77612&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=77612&r=support Expected behavior: https://bugs.php.net/fix.php?id=77612&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=77612&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=77612&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=77612&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=77612&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=77612&r=dst IIS Stability: https://bugs.php.net/fix.php?id=77612&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=77612&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=77612&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=77612&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=77612&r=mysqlcfg
