Worker 类

(PECL pthreads >= 2.0.0)

简介

Worker 是一个具有持久化上下文的线程对象，通常用来在多个线程中使用。

当一个 Worker 对象开始之后，会执行它的 run 方法，但是即使 run 方法执行完毕，线程本身也不会消亡，除非遇到以下情况：

  • Worker 对象超出作用范围（没有指向它的引用了）
  • 代码调用了 Worker 对象的 shutdown 方法
  • 整个脚本终止了

这意味着程序员可以在程序执行过程中重用这个线程上下文： 在 Worker 对象的栈中添加对象会激活 Worker 对象执行被加入对象的 run 方法。
