com_invoke - Calls a COM component's method [deprecated]

DESCRIPTION
       mixed com_invoke (resource  $com_object, string	$function_name, [mixed	$function_parameters])

       com_invoke(3) invokes the method named $function_name of the COM component referenced by $com_object. com_invoke(3) returns FALSE on error,
       returns the $function_name's return value on success. All the extra  parameters	$function_parameters  are  passed  to  the  method  $func-
       tion_name.

       Example #1

	      Don't use com_invoke(), use OO syntax instead

	      <?php
	      // do this
	      $val = $obj->method($one, $two);
	      // instead of this:
	      $val = com_invoke($obj, 'method', $one, $two);
	      ?>

       Note

	       This  function does not exist in PHP 5; instead, you should use the regular and more natural OO syntax to access properties or call
	      methods.
