Description:
------------
php manual says RecursiveDirectoryIterator::hasChildren()

Returns whether current entry is a directory and not '.' or '..' () 




Reproduce code:
---------------
<?php
$obj = new RecursiveDirectoryIterator("bbb");
$obj->rewind();
for($i=0;$i<5;$i++){
var_dump($obj->key());
var_dump($obj->hasChildren());
$obj->next();
}
?>


   directory bbb included:
1.txt   ccc    p.txt      //ccc is a directory

Expected result:
----------------
string(9) "bbb/1.txt"
bool(false)
string(7) "bbb/ccc"
bool(true)
string(9) "bbb/p.txt"
bool(false)
string(4) "bbb/"
bool(false)
string(4) "bbb/"
bool(false)


Actual result:
--------------
string(9) "bbb/1.txt"
bool(false)
string(7) "bbb/ccc"
bool(true)
string(9) "bbb/p.txt"
bool(false)
string(4) "bbb/"
bool(true)
string(4) "bbb/"
bool(true)
