# com_event_sink

(PHP 4 >= 4.2.0, PHP 5)

com_event_sink — Connect events from a COM object to a PHP object

### Beschreibung

bool com_event_sink ( variant `$comobject` , object `$sinkobject` [, mixed `$sinkinterface` ] )

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.

### Parameter-Liste

`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.

### Rückgabewerte

Gibt bei Erfolg `TRUE` zurück. Im Fehlerfall wird `FALSE` zurückgegeben.

### Beispiele

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;
?>`
