Now this is what happens: I include a .php-file for database access via ODBC. While I was trying to make things 'easier', I stumbled across a problem: Classes and functions declared in an included file seem to work at first glance, but when reloaded, the declaration fails: 

Fatal error: Cannot redeclare class odbc_obj in E:\Web-Projekte\Test\odbc.php on line 5

If I move the declaration of the class into the index.php, the script complains about being unable to redeclare connexecute(). Reloading again after the error, the script works, but thereafter, it refuses again and so on and on.


--- odbc.php ---

$conn_id = odbc_pconnect ("TEST", "", "");
global $conn_id;

class odbc_obj {
    var $result;
  
    function set_rs ($res) {
        $this->result = $res;
    }

    function out ($eingabe) {
        $retval = odbc_result($this->result,$eingabe);
        return $retval;
    }
}

function ConnExecute($sql)
{
  global $conn_id,$did;
  $did = odbc_exec ($conn_id, $sql);

  $retval = new odbc_obj;
  $retval->set_rs ($did);
  return $retval;
}

--- index.php ---
include("odbc.php");

$sql = "<some sql query string>";
$rs = ConnExecute($sql);
