Pusher: Trigger pusher when mysql data change

Question

I'm trying to use Pusher for making a real time push notification. I want to trigger the pusher when mysql data is change. Can someone help me with it? I'm new on this pusher.

The simplest way to to do this is to trigger an event via Pusher after you have performed the database interaction.

eg

// Connect and interact with database
$mysqli = new mysqli("server", "username", "password", "database_name");

$value = $_POST["activity-name"];
$stmt = $mysqli->prepare("INSERT INTO activities (column) VALUES (?)");
$stmt->bind_param("s", $value);
$stmt->execute();

// TODO: check the INSERT was successful.

$stmt->close();
$mysqli->close();

// TODO: Only trigger if the DB interaction was successful

// Create Pusher instance (assuming the Pusher library has been required)
$pusher = new Pusher(APP_KEY, APP_SECRET, APP_ID);

// Trigger the event representing the new data that's been inserted
$pusher->trigger('activities', 'activity-created' ['name' => $value]);

If the database interact were for an UPDATE then you can use a different event name.

$pusher->trigger('activities', 'activity-updated' ['name' => $value]);

Alternatively you could set up a database trigger and have another script execute and interact with Pusher when a change takes place. See Invoking a PHP script from a MySQL trigger
