In case someone needs a skeleton sink for ADODB.Connection events:
class ADOConnectionEventSink {
function BeginTransComplete( $translevel, $objerror, $status, $objconn ) {
return 0;
}
function CommitTransComplete( $objerror, $status, $objconn ) {
return 0;
}
function RolbackTransComplete( $objerror, $status, $objconn ) {
return 0;
}
function WillConnect ( $ConnectionString, $userid, $psword, $options, $status, $objconn ) {
return 0;
}
function ConnectComplete ( $objerror, $status, $objconn) {
return 0;
}
function Disconnect( $status, $objConn ) {
return 0;
}
function WillExecute ( $src, $cursortyp, $locktyp, $options, $status, $objcomm, $objrs, $objconn ) {
return 0;
}
function ExecuteComplete ( $recaffected, $objerror, $status, $objcomm, $objrs, $objconn ) {
return 0;
}
function InfoMessage ( $objerror, $status, $objconn) {
return 0;
}
}
// later on...
$db = new COM("ADODB.Connection", NULL, $charPage);
$sink = new ADOConnectionEventSink();
com_event_sink($db, $sink, "ConnectionEvents");
//...

com_event_sink — Connect events from a COM object to a PHP object
Açıklama
Instructs COM to sink events generated by comobject into the PHP object sinkobject .
Be careful how you use this feature; if you are doing something similar to the example below, then it doesn't really make sense to run it in a web server context.
Değiştirgeler
- comobject
-
- sinkobject
-
sinkobject should be an instance of a class with methods named after those of the desired dispinterface; you may use com_print_typeinfo() to help generate a template class for this purpose.
- sinkinterface
-
PHP will attempt to use the default dispinterface type specified by the typelibrary associated with comobject , but you may override this choice by setting sinkinterface to the name of the dispinterface that you want to use.
