com_event_sink

(PHP 4 >= 4.2.0, PHP 5)

com_event_sinkConnect events from a COM object to a PHP object

说明

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.

参数

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.

返回值

如果成功则返回 TRUE,失败则返回 FALSE

范例

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.php.net");
while(!
$sink->terminated) {
  
com_message_pump(4000);
}
$ie null;
?>
