amphp/mysql
===========

[](#amphpmysql)

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
--------

[](#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](https://dev.mysql.com/doc/internals/en/client-server-protocol.html)

Installation
------------

[](#installation)

This package can be installed as a [Composer](https://getcomposer.org/) dependency.

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']
}
```
