三十二、Swoole 基础学习笔记 - Swoole 协程容器
hi，我是温新，一名PHPer
文章基于 Swoole 5.0.1 版本编写。
学习目标：学习协程容器

所有的协程必须在协程容器中创建，Swoole 程序启动时大部分情况会自动创建协程容器，用 Swoole 启动程序的方式一共有三种：
- 1、调用异步风格服务端程序的 start 方法，此种启动方式会在事件回调中创建协程容器；
- 2、调用 Swoole 提供的 2 个进程管理模块 Process 和 Process\Pool 的 start 方法，此种启动方式会在进程启动的时候创建协程容器；
- 3、其他直接裸写协程的方式启动程序，需要先创建一个协程容器（
Coroutine\run()函数，可以理解为 java、c 的 main 函数）。

协程容器
Swoole\Coroutine\run()函数其实是对Swoole\Coroutine\Scheduler类（协程调度器）的封装。
下面是对 Scheduler 类的相关方法学习。
相关方法
set
含义：设置协程运行时参数。
语法：
<span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(18, 170, 228) !important">Swoole\Coroutine\Scheduler</span><span style="box-sizing: border-box;color: rgb(86, 182, 194) !important">-></span><span style="box-sizing: border-box;color: rgb(18, 170, 228) !important">set</span>(<span style="box-sizing: border-box;color: rgb(198, 120, 221) !important">array</span> <span style="box-sizing: border-box;color: rgb(224, 108, 117) !important">$options</span>): <span style="box-sizing: border-box;color: rgb(18, 170, 228) !important">bool</span></span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(98, 151, 85) !important"># 参数：该参数选项等同于协程容器中的 set() 方法参数。</span></span>
add
含义：添加任务。
语法：
<span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(18, 170, 228) !important">Swoole\Coroutine\Scheduler</span><span style="box-sizing: border-box;color: rgb(86, 182, 194) !important">-></span><span style="box-sizing: border-box;color: rgb(18, 170, 228) !important">add</span>(<span style="box-sizing: border-box;color: rgb(18, 170, 228) !important">callable</span> <span style="box-sizing: border-box;color: rgb(224, 108, 117) !important">$fn</span>, ... <span style="box-sizing: border-box;color: rgb(224, 108, 117) !important">$args</span>): <span style="box-sizing: border-box;color: rgb(18, 170, 228) !important">bool</span></span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(98, 151, 85) !important"># 参数：</span></span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"> <span style="box-sizing: border-box;color: rgb(224, 108, 117) !important">$fn</span><span style="box-sizing: border-box;color: rgb(18, 170, 228) !important">：回调函数；</span></span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"> <span style="box-sizing: border-box;color: rgb(224, 108, 117) !important">$args</span><span style="box-sizing: border-box;color: rgb(18, 170, 228) !important">：可选参数，将传递给协程</span></span>
与
go函数不同，这里添加的协程不会立即执行，而是等待调用start方法时，一起启动并执行。如果程序中仅添加了协程，未调用start启动，协程函数$fn将不会被执行。
getOptions
含义：获取设置的协程运行时参数。
语法：
<span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(18, 170, 228) !important">Swoole\Coroutine\Scheduler</span><span style="box-sizing: border-box;color: rgb(86, 182, 194) !important">-></span><span style="box-sizing: border-box;color: rgb(18, 170, 228) !important">getOptions</span>(): <span style="box-sizing: border-box;color: rgb(209, 154, 102) !important">null</span><span style="box-sizing: border-box;color: rgb(86, 182, 194) !important">|</span><span style="box-sizing: border-box;color: rgb(198, 120, 221) !important">array</span></span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(98, 151, 85) !important"># 参数：该参数选项等同于协程容器中的 getOptions() 方法参数。</span></span>
start
含义：启动程序。
语法：Swoole\Coroutine\Scheduler->start(): bool
返回值：
启动成功，会执行所有添加的任务，所有协程退出时 start 会返回 true；
启动失败返回 false，原因可能是已经启动了或者已经创建了其他调度器无法再次创建。
遍历
add和parallel方法添加的协程任务，并执行。
parallel
含义：添加并行任务。
语法：
