PHP中的框架众多，我自己就接触了好几个。大学那会啥也不懂啥也不会，拿了一个ThinkPHP学了。也许有好多人吐槽TP，但是个人感觉不能说哪个框架好，哪个框架不好，再不好的框架你能把源码读上一遍，框架的设计思想理解了也能学到好多东西。况且有好多东西自己还不理解，所以认真学习一个框架这还是可以学不少东西的。
还是先说说Laravel吧，现在已经到5.2了。就我自己来说之前没有接触过laravel，但是学习过laravel之后感觉这个框架确实不错，并且老外用的不亦乐乎。他的开发社区还可以，文档比较齐全，但是官网文档不咋地，从上面读不出多少东西（自己感觉），好多东西还得阅读源码，对于我这种英语不好的人还更喜欢中文文档（以后得改）。Laravel是使用Composer（https://getcomposer.org）来管理依赖，确实比较方便，但是因为镜像被墙的原因在访问或者更新的时候比较慢（几乎失败），这里有解决办法：http://pkg.phpcomposer.com/#tip1。
最近因为工作需要项目要重构（重构原因不用多说，大家懂得），需要迁移到新的框架上。Laravel是一个不错的框架，强大的路由，便捷的配置，高可用的模块依赖，确实为开发省了不少力气。考虑到我们这个项目主要是接口部分，对性能有一定的要求（但是不是苛刻），并且路由不能改，要兼容老的逻辑，所以Laravel是首选，但是有一个问题就是我们是写接口，那么要依赖的东西就少很多，比如view层几乎用不到，还有就是测试模块，上传模块（有图床），本地化模块文件系统等也用不到，所以使用Laravel还是比较浪费的，说白了他比较重。所以我们就考虑了基于laravel的一个框架Lumen，相比Laravel这个全栈框架而言Lumen精简了不少，并且Lumen是面向Api的，所以最后就选择Lumen了。
laravel也不是全能的有优点也有缺点，比如他的依赖太多，可以看一下安装好的laravel框架默认的依赖源包就有30M左右，确实有点大。直到今天在使用过程中发现Lumen也是有点力不从心，随着业务逻辑越来越复杂，访问速度各方面也下来了，我们有时候考虑 slim 等更轻量级的，其实吧新浪这边不少人是鸟哥粉，不少人推崇yaf，yaf确实牛逼，实践证明快的不止一点两点，估计以后还得迁移到yaf。这段时间PHP7不是出了吗，但是测试结果表明Bug不少，把接口迁移到7上应该有不少的性能提升，据说是提高100%，还没敢尝试，等稳定了再说吧！
说了不少废话，下面我就介绍一下Laravel中的日志与上传，慢慢来，这篇文章先写一部分，因为Laravel东西比较多，其他的我会慢慢写出来。我就说说自己在使用过程中遇到的问题，遇到的坑，帮助大家学习。
一、日志
1、说明：
日志重要性不言而喻，我们这边的日志是人工推荐，兴趣爱好，推荐位的依赖。做推荐的同学比写接口的还要多，日志出了问题，推荐就会不准确甚至无法推荐，可见日志的重要性。
Laravel框架初始化好了以后错误和异常处理已经默认配置好了，他的日志是基于一款很好用的日志管理工具Monolog，
首先说一下Monolog，是php下比较全又容易扩展的记录日志组件。其中Symfony 、 CakePHP等知名php框架都内置了Monolog，有兴趣的可以看一下。每个Logger实例都有一个通道和日志处理器栈。每当你添加一条日志记录，它会被发送到日志处理器栈。 你可以创建很多Logger，每个Logger定义一个通道（db，请求，路由），每个Logger有很多日志处理器。这些通道会过滤日志。每个日志处理器都有一个Formatter（内置的日志显示格式处理器）。你还可以设定日志级别。(官网解释)
日志配置：Laravel目前支持四种日志处理器，
<span>1</span> <span>S</span><span><span>ingle</span>（将日志记录到单个文件中。该日志处理器对应，对应StreamHandler）， </span><span>2</span> <span>3</span> <span>D</span><span><span>aily</span> （以日期为单位将进行日志记录对应RotatingFileHandler) </span><span>4</span> <span>5</span> <span>S</span><span>yslog</span><span>（将日志记录到Syslog中。对应SysLogHandler） </span><span>6</span> <span>7</span> <span>Errorlog</span>（将日志记录到PHP的error_log中。对应ErrorLogHandler)
明白了日志的处理方式我们就可以设置自己需要的方式，在 config/app.php中的对应项设置（默认的）：
<span>1</span> 'log' => 'single',
2、使用Log记录日志
Laravel提供了Log方法记录日志，Log实际上使用的 Illuminate\Log\Writer，应为在其中 Writer 的构造函数中注入了Monolog\Logger。生成的日志文件存放在storage/logs目录下。
如下：
<span>1</span> <span>Log</span>::emergency(<span>$error</span>); <span>//</span><span>紧急，如系统挂掉</span> <span>2</span> <span>Log</span>::alert(<span>$error</span>); <span>//</span><span>需要立即采取行动，如数据库异常等</span> <span>3</span> <span>Log</span>::critical(<span>$error</span>); <span>//</span><span>严重问题，如异常</span> <span>4</span> <span>Log</span>::error(<span>$error</span>); <span>//</span><span>运行时错误，不需要立即处理但需要被记录和监控</span> <span>5</span> <span>Log</span>::warning(<span>$error</span>); <span>//</span><span>警告但不是错误，比如使用了被废弃的API</span> <span>6</span> <span>Log</span>::notice(<span>$error</span>); <span>//</span><span>普通但值得注意的事件</span> <span>7</span> <span>Log</span>::info(<span>$error</span>); <span>//</span><span>感兴趣的事件，比如登录、退出</span> <span>8</span> <span>Log</span>::debug(<span>$error</span>); <span>//</span><span>详细的调试信息</span>
3、按照自己的需求记录日志
Laravel中如果按照原来的配置貌似不能按照自己的需求记录日志，我就按照自己的需求写了一个，供大家参考，当然你可以跳过他提供的日志处理方法Log，在容器中把 Monolog对象写入容器，可以写成单例的形式，这样在加载的时候只实例化一次，然后按照monolog来配置自己想要的记录日志的方法。

</span><span>57</span> <span> }
</span><span>58</span> <span> }
</span><span>59</span> }使用的时候可以指定，如下：
<span>1</span> Save_log::<span>error_log</span>(<span>$info</span>, 'error'<span>); </span><span>2</span> Save_log::debug_log(<span>$info</span>);
日志内容如下：
二、上传文件。
Laravel中的上传文件是基于Flysystem提供的文件系统来实现上传，删除，移动。他支持多种驱动，还有一个值得看的云存储，在SAE上需要用到。
文件系统配置位于Config/filesystems.php，我使用的试本地驱动。Laravel中的上传目录有两个：public和Storage两个，有人说这两个一样，其实是有区别的，应该说是各有好处，如果放在public中，服务器可以直接控制访问，方便效率高，放在Storage中可以加上用户控制比如权限等。
上传需要的函数如下：
判断是否进行了上传，是否存在文件:
<span>1</span> <span>$request</span>->hasFile('file')判断上传是否出错:
<span>1</span> <span>$file</span> = <span>$request</span>-><span>file</span>('file'<span>);
</span><span>2</span> <span>//</span><span>判断文件上传过程中是否出错</span>
<span>3</span> <span>if</span>(!<span>$file</span>-><span>isValid()) {
</span><span>4</span> <span>exit</span>('文件上传出错！'<span>);
</span><span>5</span> }确定上传:
<span>1</span> <span>$bytes</span> = Storage::<span>put( </span><span>2</span> <span>$savePath</span>, <span>3</span> <span>file_get_contents</span>(<span>$file</span>-><span>getRealPath()) </span><span>4</span> );
你也可以使用：
<span>$path</span> = <span>$file</span> -> move('storage/uploads');生成缩略图
Laravel木有提供函数生成缩略图，但是我们可以借助强大的Composer来引入图片处理库 Integration/Image
在项目根目录中的composer.json中的require中添加："intervention/image": "dev-master"，如下图：
然后在config/app.php中providers数组中添加：
<span>1</span> Intervention\Image\ImageServiceProvider::<span>class</span>
在aliases数组中添加别名：
<span>1</span> 'Image' => Intervention\Image\Facades\Image::<span>class</span>,
这样就可以使用了，在类文件中添加：
<span>1</span> <span>use</span> Image;
下面是添加水印并且生成缩略图：
<span>$Image</span>->text('@ u/'. <span>$user_id</span>, <span>$news_width</span> - 40 - <span>$length</span> * 10, <span>$news_height</span> - 24, <span>function</span>(<span>$font</span><span>) {
</span><span>$font</span>-><span>file</span>('public/foos.ttf'<span>);
</span><span>$font</span>->size(14<span>);
</span><span>$font</span>->color('#ffffff'<span>);
});</span>最后附上整个源码，其中生成缩略图部分可以抽象出来，因为有好几个地方都需要用到，并且水印还有看图片大小等等。
