Function name: socket_addrinfo_bind()
Applicable version: PHP 5.4.0 and above
Usage: The socket_addrinfo_bind() function is used to bind a socket to a specified address.
Syntax: bool socket_addrinfo_bind ( resource $socket , resource $addrinfo )
parameter:
Return value: Return true if successful binding is returned, and false if failed.
Example: The following example demonstrates how to bind a socket to a specified address using the socket_addrinfo_bind() function.
// 创建套接字$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); // 获取地址信息$addrinfo = socket_addrinfo_lookup("example.com", "http"); // 绑定套接字到地址if (socket_addrinfo_bind($socket, $addrinfo)) { echo "套接字绑定成功!"; } else { echo "套接字绑定失败!"; } // 关闭套接字socket_close($socket);
In the above example, a TCP socket is first created using the socket_create() function. Then use the socket_addrinfo_lookup() function to obtain the address information of the specified address. Finally, use the socket_addrinfo_bind() function to bind the socket to that address. If the binding is successful, the output will be "Socket binding is successful!", otherwise the output will be "Socket binding failed!". Finally, use the socket_close() function to close the socket.
