How to use socket_wsaprotocol_info_import in conjunction with PHP database for network data storage

gitbox 2025-05-28

1. Pre-knowledge

This is an interface or function used to process WebSocket protocol data. It is responsible for extracting additional information related to the WebSocket protocol from the underlying socket connection.
Database Operation <br> This article takes MySQL as an example to introduce how to use PHP's PDO extension to connect to the database and insert data.
PHP Socket Programming
PHP provides socket-related functions, which can create socket services and listen to network data.

2. Implementation ideas

Create a socket service through PHP to listen for network connections to the specified port.
After receiving network data, call socket_wsaprotocol_info_import to resolve the protocol-related information.
Store the parsed data into the MySQL database.
Design a reasonable data table structure to facilitate storing and querying network data.

3. Specific code examples

1. Create a database table

 CREATE TABLE websocket_data (
    id INT AUTO_INCREMENT PRIMARY KEY,
    client_ip VARCHAR(45) NOT NULL,
    protocol_info TEXT NOT NULL,
    received_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

2. PHP code examples

 <?php
// Database configuration
$dsn = 'mysql:host=gitbox.net;dbname=testdb;charset=utf8mb4';
$username = 'root';
$password = 'your_password';

try {
    $pdo = new PDO($dsn, $username, $password);
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
    die("Database connection failed: " . $e->getMessage());
}

// create socket Serve
$host = '0.0.0.0';
$port = 9501;

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if ($socket === false) {
    die("create socket fail: " . socket_strerror(socket_last_error()));
}

if (!socket_bind($socket, $host, $port)) {
    die("Bind socket fail: " . socket_strerror(socket_last_error($socket)));
}

if (!socket_listen($socket)) {
    die("monitor socket fail: " . socket_strerror(socket_last_error($socket)));
}

echo "Serve已启动，monitor端口 $port\n";

while (true) {
    $client = socket_accept($socket);
    if ($client === false) {
        echo "接受连接fail: " . socket_strerror(socket_last_error($socket)) . "\n";
        continue;
    }

    // Get the client IP
    socket_getpeername($client, $client_ip);

    // Read data
    $buffer = socket_read($client, 2048);

    // Assumptions socket_wsaprotocol_info_import It is a function of the parsing protocol
    // Here we use pseudo-code instead of specific implementation
    $protocol_info = socket_wsaprotocol_info_import($buffer);

    // Insert the database
    $stmt = $pdo->prepare("INSERT INTO websocket_data (client_ip, protocol_info) VALUES (?, ?)");
    $stmt->execute([$client_ip, json_encode($protocol_info)]);

    // Close client connection
    socket_close($client);
}

socket_close($socket);

/**
 * simulation socket_wsaprotocol_info_import function
 * Analysis WebSocket Agreement-related information
 */
function socket_wsaprotocol_info_import(string $data): array {
    // 这里应当实现真正的Analysis逻辑，This article only returns sample data
    return [
        'header' => substr($data, 0, 50),
        'payload_length' => strlen($data),
        'raw_data' => $data
    ];
}

4. Things to note

Security <br> Network data may contain malicious content, and necessary filtering and verification should be carried out before being stored in the database.
Performance optimization <br> In high concurrency scenarios, you can consider using asynchronous I/O or event-driven frameworks (such as Swoole) to improve performance.
Protocol analysis
The socket_wsaprotocol_info_import function needs to be implemented according to the specific WebSocket protocol specifications to ensure the accuracy of data parsing.
Database Design <br> Design reasonable data structures according to business needs to avoid redundancy and performance bottlenecks.
