Instructs COM to sink events generated by
|
||
|
|
<parameter>comobject</parameter> into the PHP object
|
||
|
|
<parameter>sinkobject</parameter>. PHP will attempt to use the default
|
||
|
|
dispinterface type specified by the typelibrary associated with
|
||
|
|
<parameter>comobject</parameter>, but you may override this choice by
|
||
|
|
setting <parameter>sinkinterface</parameter> to the name of the
|
||
|
|
dispinterface that you want to use.
|
||
|
|
</para>
|
||
|
|
|
||
|
|
<para>
|
||
|
|
<parameter>sinkobject</parameter> should be an instance of a class with
|
||
|
|
methods named after those of the desired dispinterface; you may use
|
||
|
|
<function>com_print_typeinfo</function> to help generate a template class
|
||
|
|
for this purpose.

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.
