socket_wsaprotocol_info_import

Function name: socket_wsaprotocol_info_import()

Function description: socket_wsaprotocol_info_import() function is used to import Winsock protocol information into PHP socket extension.

parameter:

• protocol_info (array): an associative array containing Winsock protocol information.

Return value:

• Returns the imported protocol identifier (integer) when successful, and returns false when failure.

Notes:

• Before calling this function, the socket_wsaprotocol_info_export() function must be called to export protocol information.

Example:

 // 导入Winsock协议信息$protocolInfo = array( 'iAddressFamily' => AF_INET, // 地址族'iSocketType' => SOCK_STREAM, // 套接字类型'iProtocol' => IPPROTO_TCP, // 协议'iProtocolMaxOffset' => 0, // 最大协议偏移量'szProtocol' => 'tcp', // 协议名称'dwProviderFlags' => 0, // 提供者标志'dwCatalogEntryId' => 0, // 目录项ID ); $protocolId = socket_wsaprotocol_info_import($protocolInfo); if ($protocolId !== false) { echo "Winsock协议信息导入成功，协议标识符为: " . $protocolId; } else { echo "Winsock协议信息导入失败"; }

The above example demonstrates how to import Winsock protocol information into PHP's socket extension using the socket_wsaprotocol_info_import() function. First, we create an associative array containing protocol information. Then, the socket_wsaprotocol_info_import() function is called and the protocol information is passed to the function as a parameter. If the import is successful, the protocol identifier will be returned, otherwise false will be returned. Finally, the corresponding result is output according to the return value.

Please note that before calling the socket_wsaprotocol_info_import() function, the socket_wsaprotocol_info_export() function must be called to export the protocol information. In addition, the protocol information must be exported from the same system, otherwise the import may fail.
