 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 allows to dynamically query a server with 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
 
- - 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)
- - *Full* MySQL protocol support including *all*<sup>†</sup> available commands asynchronously
