com_event_sink

(PHP 4 >= 4.2.0, PHP 5)

com_event_sink — Connect events from a COM object to a PHP object

Описание

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.

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.
