TypeSocket

A Socket instance created with socket_create.

Typestring

If the socket is of the AF_INET family, the $address is an IP in dotted-quad notation (e.g. 127.0.0.1).

OptionalTypeintDefault value0

The $port parameter is only used when binding an AF_INET socket, and designates the port on which to listen for connections.

Typebool

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.
