Description
mixed 
com_invoke ( resource com_object, string function_name [, mixed function_parameters] )
    com_invoke() invokes the method 
    named function_name of the COM
    component referenced by com_object. 
    com_invoke() returns FALSE on error, 
    returns the function_name's return 
    value on success. All the extra parameters 
    function_parameters are passed to 
    the method function_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.
