Ev EvTimer::__construct

EvTimer 클래스

(PECL ev >= 0.2.0)

EvTimer::__construct — EvTimer 감시자 객체를 생성합니다.


설명
public EvTimer::__construct(
     float $after ,
     float $repeat ,
     callable $callback ,
     mixed $data = null ,
     int $priority = 0
)

EvTimer 감시자 개체를 생성합니다.


매개변수
after
몇 초 after에 트리거되도록 타이머를 구성합니다.
repeat
repeat가 0.0이면 시간 초과에 도달하면 자동으로 중지됩니다. 양수이면 타이머가 수동으로 중지될 때까지 몇 초마다 반복적으로 다시 트리거되도록 자동으로 구성됩니다.
callback
Watcher callbacks을 참조하십시오.
data
감시자와 연결된 사용자 지정 데이터입니다.
priority
Watcher priority

Examples

예제 #1 Simple timers

                  
<?php
// Create and start timer firing after 2 seconds
$w1 = new EvTimer(2, 0, function () {
    echo "2 seconds elapsed\n";
});

// Create and launch timer firing after 2 seconds repeating each second
// until we manually stop it
$w2 = new EvTimer(2, 1, function ($w) {
    echo "is called every second, is launched after 2 seconds\n";
    echo "iteration = ", Ev::iteration(), PHP_EOL;

    // Stop the watcher after 5 iterations
    Ev::iteration() == 5 and $w->stop();
    // Stop the watcher if further calls cause more than 10 iterations
    Ev::iteration() >= 10 and $w->stop();
});

// Create stopped timer. It will be inactive until we start it ourselves
$w_stopped = EvTimer::createStopped(10, 5, function($w) {
    echo "Callback of a timer created as stopped\n";

    // Stop the watcher after 2 iterations
    Ev::iteration() >= 2 and $w->stop();
});

// Loop until Ev::stop() is called or all of watchers stop
Ev::run();

// Start and look if it works
$w_stopped->start();
echo "Run single iteration\n";
Ev::run(Ev::RUN_ONCE);

echo "Restart the second watcher and try to handle the same events, but don't block\n";
$w2->again();
Ev::run(Ev::RUN_NOWAIT);

$w = new EvTimer(10, 0, function() {});
echo "Running a blocking loop\n";
Ev::run();
echo "END\n";
?>
