Plasma provides an asynchronous, non-blocking (data access) Database Abstraction Layer. This is the core component, defining common parts and interfaces.
The core component alone does nothing, you need a Plasma driver, which does all the handling of the DBMS.
Plasma does not aim to be a full Database Abstraction Layer. Simulating missing features is not a goal and should never be.
For a list of drivers, see the main repository.
As soon as you have selected a driver, you can install it using composer. For the core, the command is
composer require plasma/core Each driver has their own dependencies, as such they have to implement a factory, which creates their driver instances correctly. For more information, see the driver project page.
But this is some little pseudo code:
$loop = \React\EventLoop\Factory::create(); $factory = new \SomeGuy\PlasmaDriver\MsSQLFactory($loop); $client = \Plasma\Client::create($factory, 'root:1234@localhost'); $client->execute('SELECT * FROM `users`', []) ->then(function (\Plasma\QueryResultInterface $result) use ($client) { // Do something with the query result // Most likely for a SELECT query, // it will be a streaming query result $client->close()->done(); }, function (\Throwable $error) use ($client) { // Oh no, an error occurred! echo $error.\PHP_EOL; $client->close()->done(); }); $loop->run();
