bool socket_connect (resource $socket, string $address, [int $port])
DESCRIPTION

PARAMETERS
o $socket
-
o $address
- The $address parameter is either an IPv4 address in dotted-quad notation (e.g. 127.0.0.1) if $socket is AF_INET, a valid IPv6
address (e.g. ::1) if IPv6 support is enabled and $socket is AF_INET6 or the pathname of a Unix domain socket, if the socket fam-
ily is AF_UNIX.
o $port
- The $port parameter is only used and is mandatory when connecting to an AF_INET or an AF_INET6 socket, and designates the port
