EvTimer::createStopped

(PECL ev >= 0.2.0)

EvTimer::createStopped — Creates EvTimer stopped watcher object

说明

final public static EvTimer::createStopped(
     float $after ,
     float $repeat ,
     callable $callback ,
     mixed $data = null ,
     int $priority = 0
): EvTimer

Creates EvTimer stopped watcher object. Unlike EvTimer::__construct() , this method doesn't start the watcher automatically.

参数

after: Configures the timer to trigger after after seconds.
repeat: If repeat is 0.0 , then it will automatically be stopped once the timeout is reached. If it is positive, then the timer will automatically be configured to trigger again every repeat seconds later, until stopped manually.
callback: See Watcher callbacks .
data: Custom data associated with the watcher.
priority: Watcher priority

返回值

Returns EvTimer watcher object on success.

范例

示例 #1 Monotor changes of /var/log/messages. Avoid missing updates by means of one second delay


<?php
$timer = EvTimer::createStopped(0., 1.02, function ($w) {
    $w->stop();

    $stat = $w->data;

    // 1 second after the most recent change of the file
    printf("Current size: %ld\n", $stat->attr()['size']);
});

$stat = new EvStat("/var/log/messages", 0., function () use ($timer) {
    // Reset timer watcher
    $timer->again();
});

$timer->data = $stat;

Ev::run();
?>
