zookeeper_dispatch — Calls callbacks for pending operations

Descrição

zookeeper_dispatch(): void

The zookeeper_dispatch() function calls the callbacks passed by operations like Zookeeper::get() or Zookeeper::exists().

Caution

Since version 0.4.0, this function must be called manually to achieve asynchronous operations. If you want that to be done automatically, you also can declare ticks at the beginning of your program.

After PHP 7.1, you can ignore this function. This extension uses EG(vm_interrupt) to implement async dispatch.
