Swoole\Timer::after

(PECL swoole >= 1.9.0)

Swoole\Timer::afterExecute a function after a specified time

Descrizione

public static function Swoole\Timer::after(int $ms, callable $callback, mixed ...$params): int|false

Creates a one-shot timer, which is destroyed once its callback has run. Unlike sleep(), it does not block the current process.

Elenco dei parametri

ms

The delay in milliseconds. Must be greater than or equal to 1; a lower value emits an E_WARNING and the call fails.

callback

The function to execute once the delay has elapsed. It is called as callback(mixed ...$params). Unlike Swoole\Timer::tick(), the timer ID is not passed to the callback.

params

Additional values passed to callback.

Valori restituiti

Returns the timer ID, which can be passed to Swoole\Timer::clear() to cancel the timer before it fires. Returns false if the timer could not be created, in particular when ms is less than 1.
