L'errore che mi dà è il seguente:

codice:
Warning: odbc_connect() [function.odbc-connect]: SQL error: [Microsoft][Driver Manager ODBC] Nome origine dati non trovato e driver predefinito non specificato., SQL state IM002 in SQLConnect in C:\xampp\htdocs\test.php on line 5 odbc not connected
Ecco anche il codice della pagina:

codice:
<?php

//connect to a DSN "myDSN"
$conn = odbc_connect('Provider=SQLOLEDB.1;Persist Security Info=False;Initial File Name=C:\Users\andrea\Desktop\DataBase\1.mdf','sa','admin');
if ($conn)
{
  //the SQL statement that will query the database
  $query = "select * from Dat_Config";
  //perform the query
  $result=odbc_exec($conn, $query);

  echo "<table border=\"1\"><tr>";

  //print field name
  $colName = odbc_num_fields($result);
  for ($j=1; $j<= $colName; $j++)
  { 
    echo "<th>";
    echo odbc_field_name ($result, $j );
    echo "</th>";
  }

  //fetch tha data from the database
  while(odbc_fetch_row($result))
  {
    echo "<tr>";
    for($i=1;$i<=odbc_num_fields($result);$i++) 
    {
      echo "<td>";
      echo odbc_result($result,$i);
      echo "</td>";
    }
    echo "</tr>";
  }

  echo "</td> </tr>";
  echo "</table >";

  //close the connection
  odbc_close ($conn);
}
else echo "odbc not connected";
?>
