全局代理程序：SOCKS5-by-weheartwebsites

A PHP5 Library to make TCP connections via a SOCKS5 Proxy.

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.
