help string:
Bind the socket to a local address. For IP sockets, the address is a
pair (host, port); the host must refer to the local host.
docs:
Bind the socket to address.
Wikipedia:
Before a socket may accept incoming connections, it must be bound.
PHP.net:
Binds the name given in address to the socket described by socket .
This has to be done before a connection is be established using
socket_connect() or socket_listen().
This function must be used on the socket before socket_connect().
