com_event_sink

(PHP 4 >= 4.2.0, PHP 5, PHP 7)

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

说明

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.

参数

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.

返回值

成功时返回 TRUE ，或者在失败时返回 FALSE 。

范例

Example #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" );
 // 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.example.org" );
while(! $sink -> terminated ) {
   com_message_pump ( 4000 );
}
 $ie  =  null ;
 ?>

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");
//...
