php - Issues with returning Array from Connection Class -

i having issue returning array.

this part of connection class.

 public function createdataset($incomingsql) {     $this->stmt = sqlsrv_query($this->conn, $incomingsql);     if ($this->stmt) {         $this->rows = sqlsrv_has_rows($this->stmt);         if ($this->rows) {             while($this->row = sqlsrv_fetch_array($this->stmt, sqlsrv_fetch_numeric))             {                             $this->myarray[] = $this->row;                     }               }           return $this->myarray;         //$this->result = $this->row;         //return $this->result;     } } 

and how calling on page...

$conn3 = new connectionclass; $mydataset = $conn3->createdataset('select top (100) city, state, postalcode store');  echo $mydataset[0]; 

i using echo test.

the $mydataset echoing nothing. can see $myarray fill 100 records when debug, not return it..
