Edit report at https://bugs.php.net/bug.php?id=53119&edit=1 ID: 53119 Updated by: cmb@php.net Reported by: marc-bennewitz at arcor dot de Summary: LimitIterator(ArrayIterator)->seek() doesn't work correctly after OutOfBoundsE -Status: Open +Status: Verified Type: Bug Package: SPL related Operating System: Linux PHP Version: 5.3.3 Block user comment: N Private report: N New Comment: Interestingly, calling ::rewind() instead of ::seek(0) works as one would expect: <https://3v4l.org/PT2qW>. Previous Comments: ------------------------------------------------------------------------ [2018-08-18 13:56:12] cmb@php.net > With php < 5.3 it works as expected. Actually, with PHP < 5.2.14 and PHP < 5.3.3, respectively[1]. The behavioral change appears to have been introduced by fixing bug #49723.

That is expected. ------------------------------------------------------------------------ [2010-10-20 20:47:02] marc-bennewitz at arcor dot de Description: ------------ Seeking after an OutOfBoundException doesn't work without call of rewind. With php < 5.3 it works as expected. Test script: --------------- $it = new ArrayIterator(array('zf9396', 'foo', null)); $it->rewind(); try { $it->seek(3); } catch (OutOfBoundsException $e) { var_dump($it->key()); $it->seek(0); var_dump($it->key()); } $lit = new LimitIterator($it, 0, 10); try { $lit->seek(3); } catch (OutOfBoundsException $e) { var_dump($lit->key()); $lit->seek(0); var_dump($lit->key()); } Expected result: ---------------- NULL int(0) NULL int(0) Actual result: -------------- NULL int(0) NULL NULL ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=53119&edit=1
