PHP 4.0 Bug #5822 Updated: key() skips the next key if element previously unset

ID: 5822 Updated by: zak Reported By: nathan@cjhunter.com Status: Closed Bug Type: Misbehaving function Assigned To: Comments: I do not believe that this is a bug. When you call unset, it shifts the elements under the unset element (if any) up to replace the missing space. So, c moves into b's spot, and then you call next... <? $a = array("a" => 1, "b" => 2, "c" => 3, "d" => 4, "e" => 5); reset($a); while($key = key($a)){ echo "Current key before unset: $key"; if($a[$key] == 2){ unset($a[$key]); } print ' | Current key after unset '. key ($a) . '<br />'; next($a); } print '<pre>'; var_dump($a); print '</pre>'; ?> Full Bug description available at: http://bugs.php.net/?id=5822
