PHP - Worker Functions


Advertisements

Worker class

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

Whenever a Worker class started, the run method can be executed. But the Thread class can't leave until one of the following conditions met −

  • Worker goes out of scope (no more references remain)
  • Programmer calls shutdown
  • Script dies

It means that a programmer can reuse the context throughout execution. Placing objects on the stack of Worker can cause the Worker to execute the stacked objects run method.
