Description:
------------
When using function next() in foreach-loop, it's not working as expected.

Reproduce code:
---------------
$row = array('A', 'B', 'C', 'D');

foreach($row as $value) {
   echo $value;
   if(next($row) !== FALSE) echo ";";
}

Expected result:
----------------
A;B;C;D

Actual result:
--------------
A;B;CD
