What would you like to do?
Mongo $exists problem
$q = array("myKey" => array('$exists'=>true));
$cursor = $mongo->db->coll->find($q);
echo $cursor->count(); // this returns the number 51
while($cursor->hasNext()){
$v = $cursor->getNext();
print_r($v); // this returns nothing
}

solved it - if you do

$q = array("myKey.Subkey" => array('$exists'=>true));

then it works. i guess it's a weird bug on php driver.
