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

SYNOPSIS

       bool com_event_sink (variant  $comobject, object  $sinkobject, [mixed  $sinkinterface])

DESCRIPTION

	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.

PARAMETERS

	      o $comobject
		-

	      o $sinkobject
		-$sinkobject should be an instance of a class  with  methods  named  after  those  of  the  desired  dispinterface;  you  may  use
		com_print_typeinfo(3) to help generate a template class for this purpose.

	      o $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.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      COM event sink example

	      <?php
	      class IEEventSinker {
		  var $terminated = false;

		 function ProgressChange($progress, $progressmax) {
		    echo "Download progress: $progress / $progressmax
";
		  }

		  function DocumentComplete(&$dom, $url) {
		    echo "Document $url complete
";
		  }

		  function OnQuit() {
		    echo "Quit!
";
		    $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;
	      ?>

define - Defines a named constant

SYNOPSIS

       bool define (string  $name, mixed  $value, [bool  $case_insensitive = false])

DESCRIPTION

	Defines a named constant at runtime.

PARAMETERS

	      o $name
		- The name of the constant.

	      o $value
		- The value of the constant; only scalar and null values are allowed. As of PHP 7 it also possible to use array value. Scalar val-
		ues are integer, float, string or boolean values. It is possible to define resource constants, however it is not  recommended  and
		may cause unpredictable behavior.

	      o $case_insensitive
		-  If  set to TRUE, the constant will be defined case-insensitive. The default behavior is case-sensitive; i.e.  CONSTANT and Con-
		stant represent different values.

	      Note

		      Case-insensitive constants are stored as lower-case.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.
