(PHP 4 >= 4.2.0, PHP 5, PHP 7, PHP 8)
com_event_sink — Connect events from a COM object to a PHP object
$variant
, object $sink_object
, array|string|null $sink_interface = null
) : bool
Instructs COM to sink events generated by
variant into the PHP object
sink_object.
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.
variant
sink_object
sink_object 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.
sink_interface
PHP will attempt to use the default dispinterface type specified by
the typelibrary associated with variant, but
you may override this choice by setting
sink_interface 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。
| 版本 | 说明 |
|---|---|
| 8.0.0 |
sink_interface is nullable now.

示例 #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");
$sink = new IEEventSinker();
com_event_sink($ie, $sink, "DWebBrowserEvents2");
$ie->Visible = true;
$ie->Navigate("http://www.example.org");
while(!$sink->terminated) {
com_message_pump(4000);
