Bug #72904 [NEW]: proc_open drops hyphenated environment variables

From: PeterJCLaw at gmail dot com Operating system: Ubuntu PHP version: 7.0.10 Package: Scripting Engine problem Bug Type: Bug Bug description:proc_open drops hyphenated environment variables Description: ------------ Environment variables with hyphens in their names (e.g: getenv('A-B')) are lost when proc_open creates a child process (other process launching functions untested). Given that these appear to be valid (they're supported by 'env' on Ubuntu) and *worked under PHP 5* this seems to be a regression. Test script: --------------- https://gist.github.com/PeterJCLaw/23719e515c787e70b614f45392dc21aa Expected result: ---------------- -- SUBPROCESS START -- A-B=ZZZ FOO=BAR getenv("INNER"): aeiou getenv("INNER-VAR"): aeiou done command returned 0 -- SUBPROCESS END -- Actual result: -------------- -- SUBPROCESS START -- A-B= FOO=BAR getenv("INNER"): aeiou getenv("INNER-VAR"): done command returned 0 -- SUBPROCESS END -- -- Edit bug report at https://bugs.php.net/bug.php?id=72904&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=72904&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=72904&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=72904&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=72904&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=72904&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=72904&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=72904&r=needscript Try newer version: https://bugs.php.net/fix.php?id=72904&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=72904&r=support Expected behavior: https://bugs.php.net/fix.php?id=72904&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=72904&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=72904&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=72904&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=72904&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=72904&r=dst IIS Stability: https://bugs.php.net/fix.php?id=72904&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=72904&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=72904&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=72904&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=72904&r=mysqlcfg
