Here's a PHP tutorial using COM connection adodb.connection Database Tutorial * *

   //access Execution Class
    class db{
        var $conn; The
       //var $rs _n;//Records the number of current Rs.
       /link
        function Create ()
        {
             $this->conn = @new com ("adodb.connection"); //This is 13 lines
             $str = "Driver=microsoft Access Driver (*.mdb);d bq=". Realpath ("./dbdata/ Yuan555.mdb ");
            $ $this->conn->open ($STR);
           //return $this-> $conn;
       }

Establish a method
function query ($sql)
{
$_rs = @new com ("Adodb.recordset");
$_rs->open ($sql, $this-> $conn, 1, 1);
return $_rs;
}
}

Instantiating classes
$DB =new db ();
$db->create ();
//--------------------------------
$rs = $db->query ("SELECT * from Product");
$rs->close ();
$rs = null; But the close is finished, it must be null.
$db->close ();
