Req #69459 [NEW]: Allow retrieving variable references from parent scope(s)

From: michaelduff2 at yahoo dot com Operating system: PHP version: Irrelevant Package: *General Issues Bug Type: Feature/Change Request Bug description:Allow retrieving variable references from parent scope(s) Description: ------------ The 'include' construct, by design, inherits the scope where it is executed which is great for templates, however: When wrapping 'include' in a function to provide augmented include() or require() functionality, there is, AFAIK, no way to retrieve references to all variables from the caller's scope so that they may be imported into the local scope and accessed by the included script. To provide this functionality, I propose adding a 'vars' element to the array returned by debug_backtrace() and a DEBUG_BACKTRACE_PROVIDE_VARS to optionally enable this functionality. Note that the resulting 'vars' arrays would be filled with references so that extract() can provide bidirectional access to those variables. Unless this can't be reasonably accomplished, I am willing to implement the necessary changes myself; please inform me how to submit the code accordingly. Thank you. -- Edit bug report at https://bugs.php.net/bug.php?id=69459&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69459&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69459&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69459&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69459&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69459&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69459&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69459&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69459&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69459&r=support Expected behavior: https://bugs.php.net/fix.php?id=69459&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69459&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69459&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69459&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69459&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69459&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69459&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69459&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69459&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69459&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69459&r=mysqlcfg
