Bug description: reset() does not work as expected on Iterator implementations
Description:
------------
The Iterator interface (SPL) defines a method rewind(). When implementing
e.g. ArrayIterator to allow array access to an object, one would expect
that reset($object) would use the rewind method. This does not happen, but
the first property is returned.
Reproduce code:
---------------
<?php
class testArray implements Iterator
{
protected $prop = array(
1 => 'one',
2 => 'two',
3 => 'three',
);
public function rewind()
{
return reset( $this->prop );
}
public function key()
{
return key( $this->prop );
}
public function current()
{
return current( $this->prop );
}
public function next()
{
return next( $this->prop );
}
public function valid()
{
return ( current( $this->prop ) !== false );
}
}
$array = new testArray();
Expected result:
----------------
// Expected: string(3) "one"
var_dump( $array->rewind() );
// Expected: string(3) "one"
var_dump( reset( $array ) );
Actual result:
--------------
// As expected: string(3) "one"
var_dump( $array->rewind() );
// Expected: string(3) "one"
var_dump( reset( $array ) );
/* Got:
array(3) {
[1]=>
string(3) "one"
[2]=>
string(3) "two"
[3]=>
string(5) "three"
}
*/
