你用中文描述吧, 我实在看不懂你说什么错误.... 
另外, 请提供一个可以正常运行的可重试脚本. 
(you can re-describe this problem in chinese, previous one is hard to read).

thanks

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

Test script:
---------------
<?php 
//OS: win7  php:5.3.16 mysql:5.5

        $moArr = SYS::getSys('sysModule'); //find module

/*

?>

Expected result:
----------------
        private function sysModule()
        {
                return array(
                                'M'=>'MODELS', 'V'=>'VIEWS',
                                'C'=>'CTRLS', 'L'=>'LIBS',
                                'P'=>'PLNS', 'H'=>'HLP'
                );
        }

error writing!
why require_once  some successful and some error
