Worker (class)

The Worker class

Introduction

(PECL pthreads >= 2.0.0)

Worker Threads have a persistent context, as such should be used over Threads in most cases.

When a Worker is started, the run method will be executed, but the Thread will not leave until one of the following conditions are met:

  • the Worker goes out of scope (no more references remain)

  • the programmer calls shutdown

  • the script dies This means the programmer can reuse the context throughout execution; placing objects on the stack of the Worker will cause the Worker to execute the stacked objects run method.
