A pure PHP PostgreSQL connector that works - sometimes you just need a quick and dirty way to connect to PostgreSQL, but for any reasons you do not have access to the native driver, and you do not care about performance.
Currently only works in Linux / UNIX-like environment as it depends on "/usr/bin/hexdump"
See examples.php
composer require derekchan/pg-php
Development status : Toy. Works for me, and it supports the protocol COPY command too, which is nice.
I wrote this library as a proof of concept and to learn a bit more about different TCP protocols. The main (only?) reason for wanting to do this is to be able to write an "Event Machine" / "Twisted" type of server where you can do asynchronous I.O. to several different kinds of application endpoint, e.g. RabbitMQ, Postgres, MySql, HTTP, etc. etc.
Currently, and for the forseeable future I'll be devoting my "open source" time to my Amqphp project, but eventually I'd like to expand this to be a fast, fully asyncronous, PHP-implemented "business process server".
