#37410 [NEW]: foreach by reference exists outside of scope

From: php at kormoc dot com Operating system: Linux PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: foreach by reference exists outside of scope Description: ------------ Foreach by reference does not honour scope. Basically, this was already reported at the following two bug reports: http://bugs.php.net/bug.php?id=29992 http://bugs.php.net/bug.php?id=36240 And they were closed with bogus, saying to look at the manual. Well, the manual doesn't talk about this issue at all, infact it seems to say that it should work as expected. Also, that var should not exists beyond the scope of the foreach loop, and the developer that closed the bug seems to agree (he said for whatever weird reason, and honestly, php should cater to the normal reasons, not the weird ones, and anyone can get the same responce out of setting it manually in the foreach themselves, rather then allowing the engine to do something weird). In anycase, this should at the very least get fixed up in the documentation, but I still consider this a engine bug. Reproduce code: --------------- <?php $array = array(1,2,3); foreach( $array as &$item ); foreach( $array as $item ); print_r( $array ); ?> Expected result: ---------------- Array ( [0] => 1 [1] => 2 [2] => 3 ) Actual result: -------------- Array ( [0] => 1 [1] => 2 [2] => 2 ) -- Edit bug report at http://bugs.php.net/?id=37410&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=37410&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=37410&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=37410&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=37410&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=37410&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=37410&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=37410&r=needscript Try newer version: http://bugs.php.net/fix.php?id=37410&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=37410&r=support Expected behavior: http://bugs.php.net/fix.php?id=37410&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=37410&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=37410&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=37410&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=37410&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=37410&r=dst IIS Stability: http://bugs.php.net/fix.php?id=37410&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=37410&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=37410&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=37410&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=37410&r=mysqlcfg
