Req #77135 [NEW]: Extract with EXTR_SKIP should skip $this

From: thflori at gmail dot com Operating system: Manjaro PHP version: 7.2.12 Package: *General Issues Bug Type: Feature/Change Request Bug description:Extract with EXTR_SKIP should skip $this Description: ------------ I know that get_defined_vars() is not returning $this but for every developer it feels like a variable that is currently defined inside an object context. As you can never overwrite $this - even outside an object context it would make sense that the extract function always work as $this is defined and use the appropriate method (skip/prefix). Test script: --------------- <?php $arr = ['this' => 'hello world']; extract($arr, EXTR_SKIP); extract($arr, EXTR_PREFIX_INVALID, 'v_'); var_dump($v_hello === $arr['this']); Expected result: ---------------- bool(true) Actual result: -------------- PHP Fatal error: Uncaught Error: Cannot re-assign $this in /tmp/test.php:4 Stack trace: #0 /tmp/test.php(4): extract(Array, 1) #1 {main} thrown in /tmp/test.php on line 4 -- Edit bug report at https://bugs.php.net/bug.php?id=77135&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=77135&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=77135&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=77135&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=77135&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=77135&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=77135&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=77135&r=needscript Try newer version: https://bugs.php.net/fix.php?id=77135&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=77135&r=support Expected behavior: https://bugs.php.net/fix.php?id=77135&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=77135&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=77135&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=77135&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=77135&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=77135&r=dst IIS Stability: https://bugs.php.net/fix.php?id=77135&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=77135&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=77135&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=77135&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=77135&r=mysqlcfg
