| >在编写 PHP 应用时经常需要处理日期和时间，使用[Carbon](http://github.com/briannesbitt/carbon) 会很方便 | |
| – 继承自 PHP[DateTime](http://www.php.net/manual/en/class.datetime.php) 类的 API 扩展，它使得处理日期和时间更加简单。 | |
| Laravel 中默认使用的时间处理类就是 Carbon。 | |
| #### 安装 | |
| ``` | |
| composer require nesbot/carbon //由于 Laravel 项目已默认安装了此包，所以不需要再次执行上面的命令。 | |
| ``` | |
| #### 使用 | |
| ``` |

| **1.Unix域Socket通信** | |
| 之前简单介绍过Unix Domain Socket这种通信方式，参见：[Nginx+PHP-FPM的域Socket配置方法](http://blog.csdn.net/dc_726/article/details/9336193) | |
| Unix域Socket因为不走网络，的确可以提高Nginx和php-fpm通信的性能，但在高并发时会不稳定。 | |
| Nginx会频繁报错： | |
| connect() to unix:/dev/shm/php-fcgi.sock failed (11: Resource temporarily unavailable) while connecting to upstream |

| Sublime Text 3（以下简称 ST3）作为轻量级文本编辑器是很不错的，打开速度要比 VS Code 快不少，而且能够自动记住当前打开及尚未保存的文件。VS Code 中有一款通过 GitHub 的 GIST 在不同计算机同步设置与扩展的扩展`Settings Sync`，ST3中也有类似的扩展（但是只能同步设置），以下为安装与配置步骤： | |
| 打开 ST3，按住`Ctrl+Shift+P`，输入`Install`，并选择下图 1 中第一项。 | |

| 以前尝试部署代码到服务器的方式有用到Github Hook或者ftp，但使用起来都有各自的缺陷，然后就发现了git hooks这个方法，查了一些资料再自己尝试过后，觉得还不错，记录下简单流程。 | |
| ### 在服务器初始化一个远程git仓库 | |
| ##### `git init` 和 `git init --bare` 的区别 | |
| 初始化出来的仓库是不一样的，前者初始化的是一个普通的仓库，其中 `.git` 文件夹是隐藏的，并且能看见该仓库下所有的源码。而后者初始化出来的仓库中的文件，就是 `.git` 中的文件夹，但不能像前者那样直接浏览或修改仓库中的代码。 | |
| ##### 使用 `git init --bare` 初始化一个远程仓库。 |

| #### 前提 | |
| 1.替换php源代码 | |
| > MAMP里面PHP源码是残缺的，所以需要自己下载PHP源码编译,因为php5.6和7.0都会用到，所以特将这两个版本的源码下载 | |
| php-5.6.链接： http://cn2.php.net/get/php-5.6.34.tar.gz/from/this/mirror | |
| php-7.0链接： http://cn2.php.net/get/php-7.0.28.tar.gz/from/this/mirror | |
| 进入php安装目录,并将原php重命名（以php7.0.27为例） | |
| ``` | |
| ☁ ~ cd /Applications/MAMP/bin/php/php7.0.27/include | |
| ☁ include mv php php.old |
