[PHP-DB] - Delete records in an Access DB

[francesco]

Hi all, 
I have this problem:
I want to delete records in an Access DB. I use this code:

$query="DELETE FROM Test_Table WHERE name='franco';"; 
// the connection parameters

$path="d:/inetpub/webs/my_site/mdb-database/" ;

$db_name="test.mdb" ;

$dsource=$path.$db_name ;

$cn_string="Provider=Microsoft.Jet.OLEDB.4.0;" ;

$cn_string.="Data Source=$dsource;" ;

// connection

$cn=new COM("ADODB.Connection");

$cn->open($cn_string);

// object Recordset and send query by  Open() metod

$rs=new COM("ADODB.Recordset") ;

$rs->open($query,$cn) ;

// clean Recordset object

$rs->Release() ;

$rs=null ;

/* close connection */

$cn->Close() ;

$cn->Release() ;

$cn=null ;



but I have this error message:

Fatal error: Call to undefined function: open() in 
D:\Inetpub\webs\metagenonlinecom\canc.php on line 11


Where is the problem? Is this the correct way to delete records from an Access DB? If 
this is a bad tecnic, can you suggest me what is the correct way?

Thanks in advance to all.
