Important Note ...

The first of these methods

    Find cursor
    /
     * Get Cursor object/public
    function look ($where =array (), $fields =array ()) {
        if ($this- >testlink ()) {
            if ($fields) {return
                $where? $this->_db->find ($where, $fields): $this->_db-> Find ()->fields ($fields);
            else{return
                $where? $this->_db->find ($where): $this->_db->find ();
            }
        return false;
    }

The second method

    Public function Find ($where =array (), $field =array ()) {
        if ($this->testlink ()) {
            $this->_data = $this- >_db->find ($where, $field)->sort (Array ("_id" =>-1));
        return $this;
    }

    
     * * Get Cursor object
    /Public Function getcursor () {return
    	$this->_data;
    }

The second need is find to get the not array

Find ($where)->getcursor (); Mongocursor Object

Pay attention.
Find () returns the current object

The ToArray () method converts the current object to an array

The GetCursor () method converts the current object to the Mongocursor object (Cursor objects)
