When using next($var) on an array containing an empty string or 0, next will stop at that item. $var=array("a"=>"aaaa","b"=>"","c"=>"cccc"); reset($var); do{ echo current($var)."\n"; }while(next($var)); this should print: aaaa cccc but it prints: aaaa The null value is not printed and the loop is stopped. When you loop over it with: for($counter=0;$counter<count($var);$counter++){ echo current($var)."\n"; next($var); } The output will be as it should be so my guess is that next returns false on null values. Foreach does it correctly as well. ---- Manual Page -- http://www.php.net/manual/en/function.next.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+36488 Delete -- http://master.php.net/manage/user-notes.php?action=delete+36488&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+36488&report=yes Search -- http://master.php.net/manage/user-notes.php
