(PHP 4 >= 4.2.0, PHP 5)
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.
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.
成功时返回 TRUE， 或者在失败时返回 FALSE。
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;
?>
