(PHP 4)
com_invoke — Calls a COM component's method [deprecated]
   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.
