Description

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

callback

See Watcher callbacks .

data

Custom data associated with the watcher.

priority

Watcher priority

Return Values

Returns EvTimer watcher object on success.

Examples

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();
?>
