From: Operating system: Arch Linux PHP version: 5.3.8 Package: Arrays related Bug Type: Bug Bug description:Iterating an array twice w and w/o references changes last item to second last
Description: ------------ Iterating an array twice, first time with references, second time *without* references, will trigger a bug in the second iteration where the last item of the array is overwritten by the second last item in the array. This seem to be the same bug as #46123, which was dismissed on erroneous grounds Test script: --------------- <? # For a more verbose look at this bug, watch http://pastebin.com/gq2qekYh $array = array('a', 'b', 'c', 'd'); # testing array foreach ($array as &$a) {} foreach ($array as $a) {} echo join(',', $array); # will produce a,b,c,c *not* a,b,c,d as expected die(); ## while, these will work as expected # 1 foreach ($array as $a) {} print_r($array); die(); # 2 foreach ($array as &$a) {} print_r($array); die(); # 3 foreach ($array as &$a) {} foreach ($array as &$a) {} print_r($array); die(); # 4 foreach ($array as $a) {} foreach ($array as $a) {} print_r($array); die(); # 5 foreach ($array as $a) {} foreach ($array as &$a) {} print_r($array); die(); ?> Expected result: ---------------- a,b,c,d Actual result: -------------- a,b,c,c -- Edit bug report at https://bugs.php.net/bug.php?id=60534&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=60534&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=60534&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=60534&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=60534&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=60534&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=60534&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=60534&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=60534&r=needscript Try newer version: https://bugs.php.net/fix.php?id=60534&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=60534&r=support Expected behavior: https://bugs.php.net/fix.php?id=60534&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=60534&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=60534&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=60534&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=60534&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=60534&r=dst IIS Stability: https://bugs.php.net/fix.php?id=60534&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=60534&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=60534&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=60534&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=60534&r=mysqlcfg
