# socket_bind

(PHP 4 >= 4.1.0, PHP 5)

socket_bind -- Binds a name to a socket

## Description

bool socket_bind ( resource socket, string address [, int port] )

socket_bind() binds the name given in address to the socket described by socket, which must be a valid socket resource created with socket_create().

The address parameter is either an IP address in dotted-quad notation (e.g. 127.0.0.1), if the socket is of the `AF_INET` family; or the pathname of a Unix-domain socket, if the socket family is `AF_UNIX`.

The port parameter is only used when connecting to an `AF_INET` socket, and designates the port on the remote host to which a connection should be made.

成功回傳`TRUE`失敗回傳`FALSE`。 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 that socket_last_error() is reported to return an invalid error code in case you are trying to bind the socket to a wrong address that does not belong to your Windows 9x/ME machine.

See also socket_connect(), socket_listen(), socket_create(), socket_last_error() and socket_strerror().
