Note: This repository is part of Dazzle Project - the next-gen library for PHP. The project's purpose is to provide PHP developers with a set of complete tools to build functional async applications. Please, make sure you read the attached README carefully and it is guaranteed you will be surprised how easy to use and powerful it is. In the meantime, you might want to check out the rest of our async libraries in Dazzle repository for the full extent of Dazzle experience.

Provided Example(s)

Quickstart

This example demonstrates how to connect to PgSQL database and print all tables stored inside it.

$loop = new Loop(new SelectLoop);

$mysql = new Database($loop, [
    'endpoint' => 'tcp://127.0.0.1:3306',
    'user'     => 'root',
    'pass'     => 'root',
    'dbname'   => 'dazzle',
]);

$mysql
    ->start()
    ->then(function() use($mysql) {
        printf("Connection has been established!\n");
        printf("Connection state is %s\n", $mysql->getState());
    })
    ->done(null, function($ex) {
        printf("Error: %s\n", var_export((string) $ex, true));
    });

$mysql->query('SHOW TABLES')
    ->then(function ($command) use ($loop) {
        $results = $command->resultRows;
        $fields  = $command->resultFields;

        printf("|%-60s|\n", str_repeat('-', 60));
        printf("|%-60s|\n", ' ' . $fields[0]['name']);
        printf("|%-60s|\n", str_repeat('-', 60));

        foreach ($results as $result)
        {
            printf("| # %-56s |\n", $result[$fields[0]['name']]);
        }
        printf("|%-60s|\n", str_repeat('-', 60));
    })
    ->then(null, function($ex) {
        printf("Error: %s\n", var_export((string) $ex, true));
    })
    ->done(function() use($loop) {
        $loop->stop();
    });

$loop->start();

Versioning

Versioning of Dazzle libraries is being shared between all packages included in Dazzle Project. That means the releases are being made concurrently for all of them. On one hand this might lead to "empty" releases for some packages at times, but don't worry. In the end it is far much easier for contributors to maintain and -- what's the most important -- much more straight-forward for users to understand the compatibility and inter-operability of the packages.
