tikobus/mysql

Async MySQL client built with Amp.

amphp/mysql is an asynchronous MySQL client built on the Amp concurrency framework. The library exposes a Promise-based API to dynamically query multiple MySQL connections concurrently. The client transparently distributes these queries across a scalable pool of available connections and does so using 100% userland PHP; there are no external extension dependencies (e.g. ext/mysqli, ext/pdo, etc).

Features

Asynchronous API exposing full single-threaded concurrency
Transparent connection pooling to overcome MySQL's fundamentally synchronous connection protocol
MySQL transfer encoding support (gzip, TLS encryption)
Support for all MySQL commands^†

^{† As documented in official Mysql Internals Manual}

Project Goals

Expose a non-blocking API for issuing multiple MySQL queries in parallel
Support the full MySQL protocol and all available commands asynchronously

Amp\Loop::run(function() {
    $config = Amp\Mysql\ConnectionConfig::fromString(
        "host=127.0.0.1 user=username password=password db=test"
    );
    
    /** @var \Amp\Mysql\Pool $pool */
    $pool = Amp\Mysql\pool($config);
    
    /** @var \Amp\Mysql\Statement $statement */
    $statement = yield $pool->prepare("SELECT * FROM table_name WHERE id = :id");
    
    /** @var \Amp\Mysql\ResultSet $result */
    $result = yield $statement->execute(['id' => 1337]);
    while (yield $result->advance()) {
        $row = $result->getCurrent();
        // $row is an associative array of column values. e.g.: $row['column_name']
    }
});
