1. Deprecated: Assigning the return value of new by reference is deprecated in /usr/local/www/uugui/cake/libs/object.php on line 117
将$dispatcher =& new Dispatcher();这样的语法改成$dispatcher = new Dispatcher();
2. Strict Standards: Non-static method DboFactory::getInstance() should not be called statically in /usr/local/www/uugui/app/common/public.inc.php on line 115
这是php调用静态方法的语法。
将$db = DboFactory::getInstance($config);这样的语法改成 $dboFactory = new DboFactory();$db = $dboFactory->getInstance($config); 或者将方法改成静态的（static修饰）
3. Deprecated: Function ereg() is deprecated in /usr/local/www/uugui/app/common/ipcheck.php on line 309
ereg是php匹配正则表达式的方法，将其替换为preg_match，并在原正则表达式的首尾添加/
将ereg方法用preg_match替换，$pattern = "^{$v}.*$";if(ereg($pattern,$tablename)) return "internal";改成$pattern = "/^{$v}.*$/";if(preg_match($pattern,$tablename)) return "internal";
4. Fatal error: Call-time pass-by-reference has been removed in /usr/local/www/uugui/app/models/diagram.php on line 291
将array_unshift (&$res,array("time"=>date("Y-m-d H:i:s",$curSec),"val"=>0)) ;改成array_unshift ($res,array("time"=>date("Y-m-d H:i:s",$curSec),"val"=>0)) ;
被调用的方法的参数列表含有&$,将&$替换为$
5. Notice: Undefined variable: string2 in C:\Inetpub\wwwroot\index.php on line 28
变量未定义或者初始化造成的错误
6. Warning: strftime(): It is not safe to rely on the system‘s timezone settings.
在php头部添加方法date_default_timezone_set("PRC");
这些语法问题都可以通过设置php的报错等级将其屏蔽，php设置debug等级的方法可以是php.ini（此方法作用于全局），也可以是在php头部设置error_reporting()这个方法只对当前脚本有效，web工程中index页面中如用了此方法会将php.ini设置覆盖。php.ini还可以设置屏蔽所有debug，配置选项可参看http://php.net/manual/zh/ini.php
