Exemple #1

Fichier : skipUntil.php Projet : ReactiveX/RxPHP

<?php

require_once __DIR__ . '/../bootstrap.php';
$loop = \React\EventLoop\Factory::create();
$scheduler = new \Rx\Scheduler\EventLoopScheduler($loop);
$observable = Rx\Observable::interval(1000)->skipUntil(\Rx\Observable::timer(5000))->take(3);
$observable->subscribe($stdoutObserver, $scheduler);
$loop->run();

Exemple #2

Fichier : timeout.php Projet : voryx/Rx.PHP

<?php

require_once __DIR__ . '/../bootstrap.php';
$loop = new \React\EventLoop\StreamSelectLoop();
$scheduler = new \Rx\Scheduler\EventLoopScheduler($loop);
Rx\Observable::interval(1000)->timeout(500)->subscribe($createStdoutObserver("One second - "), $scheduler);
Rx\Observable::interval(100)->take(3)->timeout(500)->subscribe($createStdoutObserver("100 ms     - "), $scheduler);
$loop->run();
// Output:
//100 ms     - Next value: 0
//100 ms     - Next value: 1
//100 ms     - Next value: 2
//100 ms     - Complete!
//One second - Exception: timeout
