Bug #75982 [NEW]: $_SERVER mostly empty with default variables_order GPCS on FastCGI/CGI

From: mattficken Operating system: Windows, any OS? PHP version: master-Git-2018-02-20 (snap) Package: *Configuration Issues Bug Type: Bug Bug description:$_SERVER mostly empty with default variables_order GPCS on FastCGI/CGI Description: ------------ When variables_order=GPCS(default), $_SERVER is only populated with PHP_SELF, REQUEST_TIME_FLOAT and REQUEST_TIME (PATH_TRANSLATED, etc... are missing). MediaWiki is broken on master. MediaWiki depends on $_SERVER['PATH_TRANSLATED']. Other apps depend on this too. Drupal and Wordpress are not affected. If variables_order is set to EGPCS then $_SERVER is populated as normal. On 7.2, 7.1, 7.0, $_SERVER is populated when variables_order=GPCS or EGPCS, so $_SERVER is populated by default. This this an intentional behavior change? Or a bug? I am still investigating, but at this time I believe this is caused by this: http://git.php.net/?p=php-src.git;a=commitdiff;h=bdf77f02f637bc0efbb55a800be1860279cc5b3e If this is an intentional behavior change, then http://php.net/manual/en/ini.core.php#ini.variables-order should be updated now or when PHP 7.3 is released (also should tell MediaWiki). Test script: --------------- Check phpinfo(); on web server. Or var_dump($_SERVER) on web server. This isn't a problem on CLI sapi. php -i includes $_SERVER -- Edit bug report at https://bugs.php.net/bug.php?id=75982&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=75982&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=75982&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=75982&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=75982&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=75982&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=75982&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=75982&r=needscript Try newer version: https://bugs.php.net/fix.php?id=75982&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=75982&r=support Expected behavior: https://bugs.php.net/fix.php?id=75982&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=75982&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=75982&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=75982&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=75982&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=75982&r=dst IIS Stability: https://bugs.php.net/fix.php?id=75982&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=75982&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=75982&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=75982&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=75982&r=mysqlcfg
