[](#plasma---)

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](https://github.com/PlasmaPHP/plasma).

Getting Started
===============

[](#getting-started)

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();
```

Cursors
=======

[](#cursors)

Cursors are a powerful way to get full control over fetching rows. Cursors allow you to control when a row (or multiple) is fetched from the database and allows your application a small memory footprint while fetching millions of rows.

Cursors return a promise and resolve with the row, an array of rows or `false` (when no more rows). Since they return a promise, you don't need to depend on events and possibly buffer rows when passing around the result.

When combining cursors with generator coroutines (such as Recoil), you get a powerful tool you already know from PDO.

```
// Inside a coroutine

/** @var \Plasma\CursorInterface  $cursor */
$cursor = yield $client->createReadCursor('SELECT * FROM `my_table`');

while($row = yield $cursor->fetch()) {
    // Process row
}
```

Support for cursors depend on the individual drivers.
