GearmanClient::setCompleteCallback — Set a function to be called on task completion

说明

public GearmanClient::setCompleteCallback(callable $callback): bool

Use to set a callback function to be called when a GearmanTask is completed, or when GearmanJob::sendComplete() is invoked by a worker (whichever happens first).

This callback executes only when executing a GearmanTask using GearmanClient::runTasks(). It is not used for individual jobs.

注意:

The callback will only be triggered for tasks that are added (e.g. by calling GearmanClient::addTask()) after calling this method.

如果没有返回语句，默认是 GEARMAN_SUCCESS。

callback(GearmanTask $task, mixed $context): int
task

调用此 callback 的任务。

context

Whatever has been passed to GearmanClient::addTask() (or equivalent method) as context.

返回值

成功时返回 true， 或者在失败时返回 false。
