#43501 [NEW]: foreach by reference corrupts the array (reopened)

From: gerry dot spm at gmail dot com Operating system: Linux PHP version: 5.2.5 PHP Bug Type: Scripting Engine problem Bug description: foreach by reference corrupts the array (reopened) Description: ------------ bug #29992 did not prove that the array was being modified by foreach, however this code does. According to var_dump() the last element starts as a "string" and after the foreach is a "reference to a string". Reproduce code: --------------- $foo = array('three', 'blind', 'mice'); var_dump($foo); foreach($foo as &$elmnt){} var_dump($foo); Expected result: ---------------- array(3) { [0]=> string(5) "three" [1]=> string(5) "blind" [2]=> string(4) "mice" } array(3) { [0]=> string(5) "three" [1]=> string(5) "blind" [2]=> string(4) "mice" } Actual result: -------------- array(3) { [0]=> string(5) "three" [1]=> string(5) "blind" [2]=> string(4) "mice" } array(3) { [0]=> string(5) "three" [1]=> string(5) "blind" [2]=> &string(4) "mice" } -- Edit bug report at http://bugs.php.net/?id=43501&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=43501&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=43501&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=43501&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=43501&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=43501&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=43501&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=43501&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=43501&r=needscript Try newer version: http://bugs.php.net/fix.php?id=43501&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=43501&r=support Expected behavior: http://bugs.php.net/fix.php?id=43501&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=43501&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=43501&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=43501&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=43501&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=43501&r=dst IIS Stability: http://bugs.php.net/fix.php?id=43501&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=43501&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=43501&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=43501&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=43501&r=mysqlcfg
