It will create a standard socket which can be used with the normal functions like fwrite(), fgets(), etc. Just be aware the connection is non-blocking.

Requirements

PHP5.4 or higher

Features

ability to set the outgoing interface (e.g. multi-ip environments)
ability to tunnel DNS over the Proxy as well, or do DNS queries local
- for example if the DNS server is trustable (like a local cache) it might be faster to do the DNS query directly than over the Proxy
minimal requirements, created socket can be used transparently with PHP built in functions.
for now, plaintext authentication implemented
