This bug has been fixed in the documentation's XML sources. Since the online and downloadable versions of the documentation need some time to get updated, we would like to ask you to be a bit patient. Thank you for the report, and for helping us make our documentation better. "It also means that the internal array pointer used by current() and similar functions is reset." Previous Comments: ------------------------------------------------------------------------ [2006-01-25 13:26:33] dmitriy dot buldakov at etadirect dot com Dear Sniper. I checked documentaion twice before the first reporting. So, I checked triply before this mail. There are no any phrase "cursor" or "pointer" on http://www.php.net/manual/en/language.types.array.php and http://www.php.net/manual/ru/language.types.array.php. And there is only one prase about "array assignment" - "You should be aware that array assignment always involves value copying. You need to use the reference operator to copy an array by reference" Also, there are no any phrase about cursor (or pointer) behavior in case of array assignment on http://www.php.net/manual/en/ref.array.php and on reset, end, next, prev, current, pos, key, each functions description pages. Perhaps I am not skilled in text reading, but I am sure that the "not a bug" dose not described in a sensible section of the manual. Please check also. ------------------------------------------------------------------------ [2006-01-25 10:46:36] [EMAIL PROTECTED] Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php ------------------------------------------------------------------------ [2006-01-25 10:18:14] dmitriy dot buldakov at etadirect dot com 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 this bug report at http://bugs.php.net/?id=36154&edit=1
