PHP 8.1.0 Released!

zookeeper_dispatch

(PECL zookeeper >= 0.4.0)

zookeeper_dispatchCalls callbacks for pending operations

Descrição

zookeeper_dispatch(): void

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

Cuidado

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.

Parâmetros

Esta função não possui parâmetros.

Valor Retornado

Não há valor retornado.

Erros

This method emits PHP warning when callback could not be invoked.
