com_event_sink — Connect events from a COM object to a PHP object
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.
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.
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.
Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben.
Beispiel #1 COM event sink example
<?php
class IEEventSinker {
var $terminated = false;
function ProgressChange($progress, $progressmax) {
echo "Download progress: $progress / $progressmax\n";
}
function DocumentComplete(&$dom, $url) {
echo "Document $url complete\n";
}
function OnQuit() {
echo "Quit!\n";
$this->terminated = true;
}
}
$ie = new COM("InternetExplorer.Application");
// note that you don't need the & for PHP 5!
$sink = new IEEventSinker();
com_event_sink($ie, $sink, "DWebBrowserEvents2");
$ie->Visible = true;
$ie->Navigate("http://www.example.org");
while(!$sink->terminated) {
com_message_pump(4000);
}
$ie = null;
?>
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");
//...
