com_event_sink
(PHP 4 >= 4.2.0, PHP 5)
com_event_sink — Connect events from a COM object to a PHP object
Описание
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.
Список параметров
- 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.
Возвращаемые значения
Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.

<?php

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) {

In case someone needs a skeleton sink for ADODB.Connection events:
class ADOConnectionEventSink {
function BeginTransComplete( $translevel, $objerror, $status, $objconn ) {
return 0;
}
function CommitTransComplete( $objerror, $status, $objconn ) {
return 0;
}
function RolbackTransComplete( $objerror, $status, $objconn ) {
return 0;
}
function WillConnect ( $ConnectionString, $userid, $psword, $options, $status, $objconn ) {
return 0;
}
function ConnectComplete ( $objerror, $status, $objconn) {
return 0;
}
function Disconnect( $status, $objConn ) {
return 0;
}
function WillExecute ( $src, $cursortyp, $locktyp, $options, $status, $objcomm, $objrs, $objconn ) {
return 0;
}
function ExecuteComplete ( $recaffected, $objerror, $status, $objcomm, $objrs, $objconn ) {
return 0;
}
function InfoMessage ( $objerror, $status, $objconn) {
return 0;
}
}
// later on...
$db = new COM("ADODB.Connection", NULL, $charPage);
$sink = new ADOConnectionEventSink();
com_event_sink($db, $sink, "ConnectionEvents");
//...
I got voice recognition working. I'm not sure why the way I called the sink function made it work but I'm more about results right now. This small example had me rolling on the floor laughing.
<?php
/*
* Search this for more info on the voice stuff:
* Automation Interfaces and Objects (SAPI 5.4)
*/
//directions:
//php friend.php
//then fire up windows voice recognition and turn it on and say stuff
$voice = new COM("SAPI.SpVoice");
print "Hit control+c to end.\n";
print "Friend: Hello friend!\n";
$voice->Speak("Hello friend!");
class listen
{
function Recognition($StreamNumber, $StreamPosition, $RecognitionType, $ISpeechRecoResult)
{
$phrase = $ISpeechRecoResult->PhraseInfo;
$text = $phrase->GetText();
print "\nYou:$text\n";
global $voice;
$say = array('oh', 'nice', 'humm', 'interesting', 'you dont say', 'uh huh', 'right', 'what', 'ha ha', 'you have got to be joking', 'right back at you buddy');
$idx = rand(0, count($say)-1);
print "Friend: " . $say[$idx] . "\n";
$voice->Speak($say[$idx]);
}
}
$recog = new COM("SAPI.SpSharedRecognizer");
$context = $recog->CreateRecoContext();
//SRERecognition = 16 (default)
//SREAllEvents = 393215
//$context->EventInterests = 393215;
//try to listen to events on context
$listen = new listen(); //event handler
if (!com_event_sink($context, $listen, "RecognizerStateChange"))
{
print "Unable to sink events\n";
exit;
}
$grammar = $context->CreateGrammar();
$i = $grammar->DictationLoad();
$s = $grammar->DictationSetState(1); //1=on, 0=off
while(true)
{
if(!com_message_pump(1000))
{
print ".";
}
}
?>
