I've exhausted all efforts at what appears to be a trivial problem, but gotten nowhere.

There is a simple Prepare statement:

$qry = $core->db->prepare("SELECT * FROM users WHERE email = '?'");
$qry->execute(array('[email protected]'));

However, no rows are returned. Running the query with the parameters hardcoded into the query results in a successful selection of one row. I've tryed many different methods of doing the prepare, but even it this most simple form it isn't working.

The PDO object is stored in a singleton called Core. PDO is using the mysql driver.
