-     The example below shows the handling of internal exceptions by 
-     triggering errors and handling them with a user defined function. It then
-     restores the original PHP error handling:
      <example>
       <title>
-       Error handling with <function>set_error_handler</function>,
-       <function>trigger_error</function> and 
-       <function>restore_error_handler</function>
+       Decide if <function>unserialize</function> caused an error, then
+       restore the original error handler.
