Bug description:foreach unexpectedly advances the internal array pointer
Description:
------------
Foreach unexpectedly advances the internal array pointer, although array is
returned by function without reference.
Test script:
---------------
<?php
class Test
{
function run()
{
$this->arr = array('item');
var_dump(key($this->arr)); // dumps 0
// this unexpectedly advances the internal array pointer
foreach ($this->getArr() as $v) {}
var_dump(key($this->arr)); // dumps NULL
}
function getArr()
{
// is NOT returned by reference
return $this->arr;
}
}
$test = new Test;
$test->run();
Expected result:
----------------
It dumps "0" in second time too.
