From: dmitriy dot buldakov at etadirect dot com Operating system: FreeBSD 5.3 PHP version: 4.4.2 PHP Bug Type: Scripting Engine problem Bug description: strange array cursor behavior during array assignment
Description: ------------ In case of assignment to a variable another variable that contains an array with positioned cursor the old array loses cursor position but array in new variable cathes it. I think - the initial array ($a) cursor should be untouched. The copied array ($c) cursor can be copied or reset, but its behavior should be documented. Reproduce code: --------------- <?php $a = array(1,2,3,4,5,6,7); $b = $a; next($a); print 'next($a); ...'."\n"; print ' current($a) = '.current($a)."\n"; print ' current($b) = '.current($b)."\n"; $c = $a; print '$c = $a; ...'."\n"; print ' current($a) = '.current($a)."\n"; print ' current($b) = '.current($b)."\n"; print ' current($c) = '.current($c)."\n"; ?> Expected result: ---------------- bash-3.00# php test.php next($a); ... current($a) = 2 current($b) = 1 $c = $a; ... current($a) = 2 current($b) = 1 current($c) = 1 bash-3.00# or bash-3.00# php test.php next($a); ... current($a) = 2 current($b) = 1 $c = $a; ... current($a) = 2 current($b) = 1 current($c) = 2 bash-3.00# Actual result: -------------- bash-3.00# php test.php next($a); ... current($a) = 2 current($b) = 1 $c = $a; ... current($a) = 1 current($b) = 1 current($c) = 2 bash-3.00# -- Edit bug report at http://bugs.php.net/?id=36154&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=36154&r=trysnapshot44 Try a CVS snapshot (PHP 5.1): http://bugs.php.net/fix.php?id=36154&r=trysnapshot51 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=36154&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=36154&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=36154&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=36154&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=36154&r=needscript Try newer version: http://bugs.php.net/fix.php?id=36154&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=36154&r=support Expected behavior: http://bugs.php.net/fix.php?id=36154&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=36154&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=36154&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=36154&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=36154&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=36154&r=dst IIS Stability: http://bugs.php.net/fix.php?id=36154&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=36154&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=36154&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=36154&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=36154&r=mysqlcfg
