* Create a socket (endpoint for communication)
* @link https://php.net/manual/en/function.socket-create.php
* @param int $domain
* The domain parameter specifies the protocol * family to be used by the socket. *
*| Domain | *Description | *
| AF_INET | ** IPv4 Internet based protocols. TCP and UDP are common protocols of * this protocol family. * | *
| AF_INET6 | ** IPv6 Internet based protocols. TCP and UDP are common protocols of * this protocol family. * | *
| AF_UNIX | ** Local communication protocol family. High efficiency and low * overhead make it a great form of IPC (Interprocess Communication). * | *
* The type parameter selects the type of communication * to be used by the socket. *
*| Type | *Description | *
| SOCK_STREAM | ** Provides sequenced, reliable, full-duplex, connection-based byte streams. * An out-of-band data transmission mechanism may be supported. * The TCP protocol is based on this socket type. * | *
| SOCK_DGRAM | ** Supports datagrams (connectionless, unreliable messages of a fixed maximum length). * The UDP protocol is based on this socket type. * | *
| SOCK_SEQPACKET | ** Provides a sequenced, reliable, two-way connection-based data transmission path for * datagrams of fixed maximum length; a consumer is required to read an * entire packet with each read call. * | *
| SOCK_RAW | ** Provides raw network protocol access. This special type of socket * can be used to manually construct any type of protocol. A common use * for this socket type is to perform ICMP requests (like ping). * | *
| SOCK_RDM | ** Provides a reliable datagram layer that does not guarantee ordering. * This is most likely not implemented on your operating system. * | *
* The protocol parameter sets the specific * protocol within the specified domain to be used * when communicating on the returned socket. The proper value can be * retrieved by name by using getprotobyname. If * the desired protocol is TCP, or UDP the corresponding constants * SOL_TCP, and SOL_UDP * can also be used. *
*| Name | *Description | *
| icmp | ** The Internet Control Message Protocol is used primarily by gateways * and hosts to report errors in datagram communication. The "ping" * command (present in most modern operating systems) is an example * application of ICMP. * | *
| udp | ** The User Datagram Protocol is a connectionless, unreliable, * protocol with fixed record lengths. Due to these aspects, UDP * requires a minimum amount of protocol overhead. * | *
| tcp | ** The Transmission Control Protocol is a reliable, connection based, * stream oriented, full duplex protocol. TCP guarantees that all data packets * will be received in the order in which they were sent. If any packet is somehow * lost during communication, TCP will automatically retransmit the packet until * the destination host acknowledges that packet. For reliability and performance * reasons, the TCP implementation itself decides the appropriate octet boundaries * of the underlying datagram communication layer. Therefore, TCP applications must * allow for the possibility of partial record transmission. * | *
