com_event_sink

Connect events from a COM object to a PHP object

Description

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.

Parameters

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.

Return Values

Returns TRUE on success or FALSE on failure.

Examples

Example #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;
?>
