socket_connect — Initiates a connection on a socket
$socket
, string $address
[, int $port = 0
] ) : bool
Initiate a connection to address using the socket resource
socket, which must be a valid socket
resource created with socket_create().
socket
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 family is
AF_UNIX.
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 on the remote host to which a connection should be made.
Returns TRUE on success or FALSE on failure. The error code can be retrieved with
socket_last_error(). This code may be passed to
socket_strerror() to get a textual explanation of the
error.
Note:
If the socket is non-blocking then this function returns
FALSEwith an errorOperation now in progress.
