提示在/var/www/html/code/BabyOnline1/utility/fun.class.php(281)文件、 /var/www/html/code/BabyOnline1/platform/php/ini.php(41)文件 /var/www/html/code/BabyOnline1/utility/mysqli5.php on line 39文件

第一个fun.class.php文件是实现的日志写入数据库的功能；

function WriterToDB($typeid,$clientAddress,$datetime,$file,$line,$function,$content)
	{
		global $utility;
		if(is_array($content))
		{
			$conn = $utility->CreateDBConnect($_SESSION["DB"]["Host"],$_SESSION["DB"]["Port"],$_SESSION["DB"]["User"],$_SESSION["DB"]["Password"],$_SESSION["DB"]["Name"],$_SESSION["DB"]["Character"]);
			$conn->Query("INSERT INTO `NMIOperationLog` (`Index`,`Operation`,`OperationTime`,`Description`,`ManageDomainUserInfo_Index`,`ManageDomain_Index`,`ManageDomainUserInfo_Identity`,`ManageDomains`,`SqlScript`)VALUES(null,'".$content["Operation"]."','".$content["OperationTime"]."','".addslashes($content["Description"])."','".$content["ManageDomainUserInfo_Index"]."','".$content["ManageDomain_Index"]."','".$content["ManageDomainUserInfo_Identity"]."','".$content["ManageDomains"]."','".addslashes($content["SqlScript"])."') ");
	
			//$log->Writer(1,"NMI",strftime("%Y-%m-%d %H:%M:%S",time()),__FILE__,__LINE__,__FUNCTION__,mysql_error());
			
		}
		return true;
	}

连库WriterToDB实现功能如上；同样的ini.php同样定义了数据库的配置信息包括类型、url和连接信息：

define('LOGSAVETYPE',1);
define('LOGLEVEL',1);

define('DB_TYPE', "mysql"); 
define('IMAGE_URL', "http://61.191.35.32:8580/BabyOnline/");
define('DB_SOURCEFILE_PATH',dirname(dirname(dirname(__FILE__)))."/utility/dbsource.ini");

dbsource.ini文件里面则详细配置了jdbc的配置信息，就不单独放出来了；再来看看最后一个文件，同样是连接数据库，然后发现了一些有趣的： 随意捡了一些构造函数：

function QueryRecordCount($sqlstr)
	{
		if($this->connect)
		{
			unset($row);
			$row=$this->FetchArray($this->Query("SELECT count(1) as RecordCount FROM ".$sqlstr." "));
			return ($row['RecordCount'] > 0 ? $row['RecordCount'] : 0);
		}
		else
		{
			return 0;
		}
	}


if($link->FetchArray($link->query("SELECT * FROM User WHERE `Identity`='$UserId' AND AreaCode='$AreaCode'")))
    {
    ···
    }

咳咳，跑偏了，以上来看就直接修改ini文件就行了。
