关于PHP日志LOG4PHP的配置与使用

本篇文章给大家介绍PHP日志LOG4PHP的配置与使用 。有一定的参考价值，有需要的朋友可以参考一下，希望对大家有所帮助。

维护了 一个老项目， 没有日志功能， 就给加了这个log4PHP， 主要是集成进去很简单，使用起来也够用了。

1、下载log4PHP

2、创建配置文件

log4PHP_config.xml

<configuration xmlns=http://logging.apache.org/log4PHP/>
    <appender name=default class=LoggerAppenderConsole />

    <appender name=basic_file_appender class=LoggerAppenderDailyFile>
        <layout class=LoggerLayoutPattern>
            <param name=conversionPattern value=%date [%logger] %message%newline />
        </layout>
        <param name=file value=log/app.%s.log /> // log文件夹下  以日期命名的log文件
        <param name=datePattern value=Y-m-d />
    </appender>
    <root>
        <level value=debug />
        <appender_ref ref=basic_file_appender/>
    </root>

    <appender name=route_file_appender class=LoggerAppenderDailyFile>
        <layout class=LoggerLayoutPattern>
            <param name=conversionPattern value=%date %p [%logger] %message%newline />
        </layout>
        <param name=file value=log/route.%s.log />
        <param name=threshold value=error/>
        <param name=append value=true />
        <param name=datePattern value=Y-m-d />
    </appender>
    <logger name=Route>
        <level value=debug />
        <appender_ref ref=route_file_appender />
    </logger>

    <appender name=session_file_appender class=LoggerAppenderDailyFile>
        <layout class=LoggerLayoutPattern>
            <param name=conversionPattern value=%date [%logger] %message%newline />
        </layout>
        <param name=file value=log/session.%s.log />
        <param name=datePattern value=Y-m-d />
    </appender>
    <logger name=Session>
        <level value=debug />
        <appender_ref ref=session_file_appender />
    </logger>

    <appender name=InventoryTransaction_file_appender class=LoggerAppenderDailyFile>
        <layout class=LoggerLayoutPattern>
            <param name=conversionPattern value=%date [%logger] %message%newline />
        </layout>
        <param name=file value=log/InventoryTransaction.%s.log />
        <param name=datePattern value=Y-m-d />
    </appender>
    <logger name=InventoryTransaction>
        <level value=debug/>
        <appender_ref ref=InventoryTransaction_file_appender />
    </logger>

    <appender name=Reserve_file_appender class=LoggerAppenderDailyFile>
        <layout class=LoggerLayoutPattern>
            <param name=conversionPattern value=%date [%logger] %message%newline />
        </layout>
        <param name=file value=/data0/wmsinventoryapi/Reserve.%s.log />
        <param name=datePattern value=Y-m-d.H />
    </appender>
    <logger name=Reserve>
        <level value=debug/>
        <appender_ref ref=Reserve_file_appender />
    </logger>

    <appender name=Exception_file_appender class=LoggerAppenderDailyFile>
        <layout class=LoggerLayoutPattern>
            <param name=conversionPattern value=%date [%logger] %message%newline />
        </layout>
        <param name=file value=log/exception.%s.log />
        <param name=datePattern value=Y-m-d />
    </appender>
    <logger name=Exception>
        <level value=error/>
        <appender_ref ref=Exception_file_appender />
    </logger>

</configuration>

3、LOG类

<?PHP
/**
 * Created by PHPStorm.
 * User: an
 * Date: 2019/4/3
 * Time: 4:35 PM
 */
require_once('vendor/log4PHP/Logger.PHP');
Logger::configure('vendor/log4PHP/log4PHP_config.xml'); // 引入第二步创建的xml配置文件

class L
{
    public static function __callStatic($name, $args)
    {
        $log = Logger::getLogger('app');

        switch ($name)
        {
            case 'error':
                $log->error($args);
                break;
            case 'info':
                $log->info($args);
                break;
            case 'warn':
                $log->warn($args);
                break;
            case 'debug':
                $log->debug($args);
                break;
            case 'fatal':
                $log->fatal($args);
                break;
            default:
                break;
        }
    }
}

4、使用【推荐学习：PHP教程】

L::debug('日志要记录的内容');
L::info('日志要记录的内容');
