EvTimer::createStopped — Creates EvTimer stopped watcher object
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.
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 Returns EvTimer watcher object on success.
Example #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();
?>
