Noticed it doesn't change the pointer if foreach just loop though the array itself (this seems to be fixed in #40705). However, as it is in the repro code, I loop though a subelement of the array, it still changes the pointer. Reproduce code: --------------- <?php function a($arr) { foreach($arr['k'] as $r) { } } $arr = array( 'k' => array(1) ); a($arr); var_dump(current($arr['k'])); Expected result: ---------------- int(1) Actual result: -------------- bool(false) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=43890&edit=1
