早说啊，我还以为都是外国人呢。
//定义网站跟目录 init.php
define('WEB_ROOT', strtr(dirname(__FILE__), '\\', '/'));
//定义网站的其它目录
define('TEMP', WEB_ROOT.DS.'temp');
define('LIBS', WEB_ROOT.DS.'libs');
define('VIEWS', WEB_ROOT.DS.'views');
//下面是我写的一个类 sys.php
class SYS
{
       
//这个是每个目录对应的简写，但是这是错误写法，可在后期的程序调用中居然有的
        //可以成功有的失败了  $moArr =
SYS::getSys('sysModule');
        //require_once($moArr[$type].DS."{$csName}.php");
这样可以直接
       
//引入所需要的文件，避免使用switch浪费时间
        /*
// 		switch($type)  以上将会获取更快执行速度

//这里是系统目录对应的单词简写，但是这是错误写法

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
//such as  [Some code snippets]
//Assume  WEB_ROOT = 'E:/www';
define('WEB_ROOT', strtr(dirname(__FILE__), '\\', '/'));

define('PLNS', WEB_ROOT.DS.'plugins');
define('CONFS', WEB_ROOT.DS.'configs');
define('MODELS', WEB_ROOT.DS.'models');
define('CTRLS', WEB_ROOT.DS.'controls');
//define  associate
/*    Error writing       */
class SYS
{
	private function sysModule()
	{
		return array(
				'M'=>'MODELS', 'V'=>'VIEWS',
				'C'=>'CTRLS', 'L'=>'LIBS',
				'P'=>'PLNS', 'H'=>'HLP'
		);
	}
	
	public static function getSys($fun)
	{
		return self::$fun();
	}	
}	

//common.php load some calss file
//Assume  $type = 'M.className';
function loadSomeClass($type)
{
	$csName = substr($cs, 2);
	$type = strtoupper(strtok($cs, '.'));
	$moArr = SYS::getSys('sysModule'); //find module
	require_once($moArr[$type].DS."{$csName}.php");
}

//bugs: In accordance with the above wording some successful and some can not successfully  ?????

/*

		);
	} 
 */

?>

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
