AMPHP is a collection of event-driven libraries for PHP designed with fibers and concurrency in mind. amphp/mysql is an asynchronous MySQL client. The library implements concurrent querying by transparently distributing queries across a scalable pool of available connections. 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

  • Exposes a non-blocking API for issuing multiple MySQL queries concurrently
  • Transparent connection pooling to overcome MySQL's fundamentally synchronous connection protocol
  • MySQL transfer encoding support (gzip, TLS encryption)
  • Support for parameterized prepared statements
  • Nested transactions with commit and rollback event hooks
  • Unbuffered results to reduce memory usage for large result sets
  • Full MySQL protocol support including all† available commands asynchronously

† As documented in official Mysql Internals Manual

Installation

This package can be installed as a Composer dependency.

composer require amphp/mysql

Requirements

  • PHP 8.1+

Usage

More extensive code examples reside in the examples directory.

use Amp\Mysql\MysqlConfig;
use Amp\Mysql\MysqlConnectionPool;

$config = MysqlConfig::fromString(
    "host=localhost user=username password=password db=test"
);

$pool = new MysqlConnectionPool($config);

$statement = $pool->prepare("SELECT * FROM table_name WHERE id = :id");

$result = $statement->execute(['id' => 1337]);
foreach ($result as $row) {
    // $row is an associative-array of column values, e.g.: $row['column_name']
}
