onMessage

Description:

callback Connection::$onMessage

The function is the same as the Worker::$onMessage callback, with the distinction that it is only effective for the current connection, which means the onMessage callback can be set for a specific connection.

Example

use Workerman\Worker;
use Workerman\Connection\TcpConnection;
require_once __DIR__ . '/vendor/autoload.php';

$worker = new Worker('websocket://0.0.0.0:8484');
// When a client connects
$worker->onConnect = function(TcpConnection $connection)
{
    // Set connection's onMessage callback
    $connection->onMessage = function(TcpConnection $connection, $data)
    {
        var_dump($data);
        $connection->send('receive success');
    };
};
// Run the worker
Worker::runAll();

The effect of the above code is the same as the one below.

use Workerman\Worker;
use Workerman\Connection\TcpConnection;
require_once __DIR__ . '/vendor/autoload.php';

$worker = new Worker('websocket://0.0.0.0:8484');
// Set onMessage callback for all connections directly
$worker->onMessage = function(TcpConnection $connection, $data)
{
    var_dump($data);
    $connection->send('receive success');
};
// Run the worker
Worker::runAll();
