I am trying to use the following to use database via a function. This is not working as expected. This works outside of the function but not in. The page returns blank when the PDO line is used.
function db($inputStatement){
        $link = new PDO("mysql:host=$dbhost;dbname=$dbname",$dbuser,$dbpass);
        $statement = $link->prepare($inputStatement);
      echo $inputStatement.'-XX';
  }
  db("SELECT * FROM users");
echo "<br />END OF test.php";
