php的日志处理类
LIB_Log.php 文件是日志处理类的代码文件
log_config.php 文件是它的配置文件
log.php 是测试文件
本日志处理类支持FATAl日志、NOTICE日志、TRACE日志、RPC日志、SYS等级日志。
FATAL日志：php异常中断日志。
NOTICE日志：请求的功能日志，每次请求只记录一条日志
TRACE日志：调用关系日志
RPC日志：对依赖接口的调用日志，调用异常后端依赖就应该记录一条RPC日志
SYS日志：对CI框架起作用，如果使用的是CI框架，用这个日志类覆盖CI的系统日志，SYS等级就是用户记录CI系统的日志。
记录NOTICE日志：
$app = 'login';//模块名称,控制日志的子目录 同时这个参数还支持`define('APP','login');`方式来支持
$logSrv = new LIB_Log();//日志类初始化
$logSrv->addlog('key', 'value');//添加NOTICE日志
$logSrv->write($app);
记录RPC日志：
$logSrv = new LIB_Log();//日志类初始化
$logSrv->rpcstart();//rpc调用的起始时间记录
$logSrv->writerpc(array('rpc_params' => 'rpc_value'));
配置文件说明
//日志配置
$config = array(
'log_path' => '/data/logs/',
'product' => 'uc',
'level' => 3,
'path' => array(
'FATAL' => 'php/php.log.',
'RPC' => 'rpc/rpc.log.',
'SYS' => 'cisys/sys.log.',
),
'suffix' => array(
'WARNING' => '.wf',
),
);
说明：
log_path:日志的根目录配置，日志将会全部记录在这个目录下，日志可能会根据模块名称不同或者日志等级不同而被记录到不同的子目录下。
product:系统名称uc代表user center
level:日志的等级。
根据代码中的：
protected $_levels = array('FATAL' => 1, 'NOTICE' => 3, 'RPC' => 3, 'WARNING' => 4, 'TRACE' => 5, 'SYS' => 6, 'ALL' => 7);
来配置日志的等级，如果配置的是3，那么系统只会记录等级小于等于4的日志，这里就是FATAL,NOTICE,RPC
path:根据这个配置，可以强制将不同等级的日志记录到不同的目录中。
suffix:根据这个配置，可以强制将不同等级的日志记录到带有后缀的文件中。
当level配置为4时：
