Bug description: function valid , next, current ..from subclass of
FilterIterator return false
Description:
------------
When extends a class with FilterIterator, the valid ,current,key, next
functions can't work, until you override your function with the following
codes
public function valid() {
$this->getInnerIterator()->valid();
}
btw, my php works version is 5.2.6, I can't found this version in the
select list , so I selected 5.2.9
Reproduce code:
---------------
error_reporting ( E_ALL | E_STRICT );
$array = array ('koala', 'kangaroo', 'wombat', 'wallaby', 'emu', 'NZ' =>
'kiwi', 'kookaburra', 'platypus' );
class CullingIterator extends FilterIterator {
public function __construct(Iterator $it) {
parent::__construct ( $it );
}
function accept() {
$ittmp = $this->getInnerIterator ();
if ($ittmp->current () == 'koala') {
return false;
}
return true;
}
}
$cull = new CullingIterator ( new ArrayIterator ( $array ) );
try {
while ( $cull->valid () ) {
echo $cull->current ();
$cull->next ();
}
} catch ( Exception $e ) {
$e->getTraceAsString ();
}
Expected result:
----------------
print out the array result as following
kangaroowombatwallabyemukiwikookaburraplatypus
Actual result:
--------------
print nothing, becuase when we call $cull->valid() will return false
additional information , I've also tracked this problem by the following
code,
$cull = new CullingIterator ( new ArrayIterator ( $array ) );
$it = $cull->getInnerIterator();
var_dump( $it->valid() );
and the result is bool(true), it's very strange to get this while we
$cull->valid() it return false(true)
