Installation

[](#installation)

```

Usage
-----

[](#usage)

Simple example with `\SIGINT` signal.

```
use Kafkiansky\Signaler\SeldSignalFactory;
use Psr\Log\NullLogger;

$factory = new SeldSignalFactory(new NullLogger());

$signaler = $factory->subscribe([
    \SIGINT => function () use ($worker): void {
        $worker->stop();
    }
]);

while ($signaler->isTriggered() === false) {
    //
}
```

The main purpose of this library is to prevent the signal listener from being replaced by the `pcntl_signal` function if it was previously configured by vendor code. The library carefully saves previous signal listeners and will call them after yours.

In e.g.:

```
use Kafkiansky\Signaler\SeldSignalFactory;
use Psr\Log\NullLogger;

pcntl_signal(\SIGINT, function (): void {
    // This function will still be called after all your listeners.
});

$factory = new SeldSignalFactory(new NullLogger());

$signaler = $factory->subscribe([
    \SIGINT => function () use ($worker): void {
        $worker->stop();
    }
]);

while ($signaler->isTriggered() === false) {
    //
}
```
