From: marc at perkel dot com Operating system: Linux PHP version: 5.2.11 PHP Bug Type: Scripting Engine problem Bug description: foreach needs to be fixed
Description: ------------ When using foreach and looping through an array the second time if the index variable isn't unset the results are that the referenced variables is used as the index rather than the named variable. The issue can be solved if when the foreach is set up that it does an unset on the variable passed as the "as" variable. PHP should be changed to unset the parameter passed as the index into the array. Reproduce code: --------------- $myarray = array("one","two","three","four"); foreach ($myarray as &$x) { $x = "$x -"; print "$x\n"; } print "\n"; foreach ($myarray as $x) { print "$x\n"; } Expected result: ---------------- one - two - three - four - one - two - three - four - Actual result: -------------- one - two - three - four - one - two - three - three - -- Edit bug report at http://bugs.php.net/?id=50161&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=50161&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=50161&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=50161&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=50161&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=50161&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=50161&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=50161&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=50161&r=needscript Try newer version: http://bugs.php.net/fix.php?id=50161&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=50161&r=support Expected behavior: http://bugs.php.net/fix.php?id=50161&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=50161&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=50161&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=50161&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=50161&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=50161&r=dst IIS Stability: http://bugs.php.net/fix.php?id=50161&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=50161&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=50161&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=50161&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=50161&r=mysqlcfg
