#40028 [NEW]: Wrong behaviour of next() and prev()

From: prometheus__0 at hotmail dot com Operating system: Linux Sles10 PHP version: 5.2.1RC2 PHP Bug Type: Scripting Engine problem Bug description: Wrong behaviour of next() and prev() Description: ------------ the bug report with id 27782 is the same as this one http://bugs.php.net/bug.php?id=27782 As stated in documentation, next() returns the NEXT element in the array and THEN increases internal pointer. Thus, when this function returns FALSE, I expect the internal pointer to be in the last position, thus prev() should return end()-1 element. i tested it with older php5 versions and it seems this bug occures within all php5 versions bug http://bugs.php.net/bug.php?id=37598 occures too Reproduce code: --------------- <?php $a = array("a", "b", "c"); reset($a); while (next($a) !== FALSE); var_dump(prev($a)); ?> Expected result: ---------------- string(1) "b" Actual result: -------------- bool(false) -- Edit bug report at http://bugs.php.net/?id=40028&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=40028&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=40028&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=40028&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=40028&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=40028&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=40028&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=40028&r=needscript Try newer version: http://bugs.php.net/fix.php?id=40028&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=40028&r=support Expected behavior: http://bugs.php.net/fix.php?id=40028&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=40028&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=40028&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=40028&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=40028&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=40028&r=dst IIS Stability: http://bugs.php.net/fix.php?id=40028&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=40028&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=40028&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=40028&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=40028&r=mysqlcfg
