README

PHP based command line key listener.

This library provides an API to capture keys from the terminal. It currently supports latin-basic range of characters such as direction keys, function keys (F*), enter, space, insert, delete, backspace, escape, a-z, etc.

Installation

You can either download this library as a zip, or simply install it via composer:

composer require atatusoft-ltd/php-key-listener

Limitations

This package only works on UNIX/Linux based systems since the Windows PHP version doesn't not support the readline extension.

Example

Capture all keys

use \Atatusoft\PhpKeyListener\Events\KeyPressEvent;
use \Atatusoft\PhpKeyListener\Environment\Detector;

$detect = new Detector();
$listener = $detect->getListenerInstance();

$eventDispatcher = $listener->getEventDispatcher();

$eventDispatcher->addListener('key:press', function(KeyPressEvent $event) {
    echo $event->getKey(), PHP_EOL;
});

$eventDispatcher->addListener('key:enter', function(KeyPressEvent $event) use ($eventDispatcher) {
    echo 'Key "', $event->getKey(), '" was pressed. Quitting listener.', PHP_EOL;

    // notify the listener to stop
    $eventDispatcher->dispatch('key:stop:listening');
});

$listener->start();
