socket_connect
- It initiates a connection on a socket
Syntax:
int socket_connect ( resource socket, string address [, int port])
It initiates a connection using the socket descriptor socket, which must be a valid socket descriptor 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.
It returns zero on success, or a negative error code on failure. This code may be passed to socket_strerror() to get a textual explanation of the error.
Example:
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_connect($socket, $address, $port);
here, it connect a host with given $address and $port by using the resource $socket.
