Bug description:SPL InfiniteIterator needs explicit rewind to be usable in a
closure
Description:
------------
SPL's InfiniteIterator returns NULL for the first access, unless used in a
'foreach' loop, or a rewind is done.
This means that an explicit rewind is needed before an InfiniteIterator can
be
safely be used in an application.
Test script:
---------------
<?php
$b = array('one', 'two', 'three');
$b_it = new InfiniteIterator(new ArrayIterator($b));
for ($i = 0; $i < 7; $i++) {
var_dump($b_it->current());
$b_it->next();
}
?>
Expected result:
----------------
string(3) "one"
string(3) "two"
string(5) "three"
string(3) "one"
string(3) "two"
string(5) "three"
string(3) "one"
Actual result:
--------------
NULL
string(3) "two"
string(5) "three"
string(3) "one"
string(3) "two"
string(5) "three"
string(3) "one"
