Description:
------------
Using PDO_informix (v1.0.0)

No data is returned and it want's to save the output as a file rather than show the output in the browser.

Removing the placeholder code and defining the record id in the SQL shows the record in the browser just fine.

Reproduce code:
---------------
$stmt = $db->prepare("select * from case where cs_caseid = :caseid");

if ($stmt->execute(array(':caseid' => '258579')) ) {
  while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
    print_r($row);
  }
}


Expected result:
----------------
Return the specified record

Actual result:
--------------
Wants to save the php output as a file rather than display in the browser.
