(PHP 4 >= 4.2.0, PHP 5, PHP 7, PHP 8)
com_event_sink — Connect events from a COM object to a PHP object
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.
variantsink_objectsink_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.
| Versão | Descrição |
|---|---|
| 8.0.0 | sink_interface is nullable now. |
