Bug #75712 [NEW]: If $_SERVER['argv'] exists in code, calls to getenv() will return argv and argc

From: adam at lavoaster dot co dot uk Operating system: linux PHP version: 7.1.12 Package: *General Issues Bug Type: Bug Bug description:If $_SERVER['argv'] exists in code, calls to getenv() will return argv and argc Description: ------------ This came out of looking into an issue here - https://github.com/symfony/symfony/issues/25511 If $_SERVER['argv'] exists anywhere in the code, it doesn't matter if it isn't called, just as long it's included, it will add 'argv' and 'argc' to the return of 'getenv()' when called without any parameters. Just a note: If you have xdebug installed, this issue will not present itself. Test script: --------------- <?php var_dump(getenv()); function notcalled() { $_SERVER['argv']; } Expected result: ---------------- It shouldn't return 'argv' or 'argc' in the return array, especially as 'argv' is an array which would break scripts that would directly use getenv(), like Symfony process did, straight into proc_open. Actual result: -------------- It returns 'argv' and 'argc' in the returning array. -- Edit bug report at https://bugs.php.net/bug.php?id=75712&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=75712&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=75712&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=75712&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=75712&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=75712&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=75712&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=75712&r=needscript Try newer version: https://bugs.php.net/fix.php?id=75712&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=75712&r=support Expected behavior: https://bugs.php.net/fix.php?id=75712&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=75712&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=75712&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=75712&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=75712&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=75712&r=dst IIS Stability: https://bugs.php.net/fix.php?id=75712&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=75712&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=75712&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=75712&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=75712&r=mysqlcfg
