PHP と swoole を使用して高性能のリアルタイムログ分析を行うにはどうすればよいですか?

$ pecl install swoole

extension=swoole.so

class LogAnalyzer
{
    private $logFile;
    private $statistics = [];

    public function __construct($logFile)
    {
        $this->logFile = $logFile;
    }

    public function analyze()
    {
        // 初始化swoole的异步文件IO
        $fp = swoole_async_read($this->logFile, function ($filename, $content) {
            $this->processLog($content);
        });

        // 添加事件循环，等待IO完成
        swoole_event_wait();

        // 输出统计结果
        foreach ($this->statistics as $ip => $count) {
            echo "$ip: $count
";
        }
    }

    private function processLog($content)
    {
        $lines = explode("
", $content);
        foreach ($lines as $line) {
            if (empty($line)) continue;
            // 解析日志行，获取IP地址
            $matches = [];
            preg_match('/(d{1,3}.d{1,3}.d{1,3}.d{1,3})/', $line, $matches);
            if (isset($matches[1])) {
                $ip = $matches[1];
                if (isset($this->statistics[$ip])) {
                    $this->statistics[$ip]++;
                } else {
                    $this->statistics[$ip] = 1;
                }
            }
        }
    }
}

$logFile = 'access.log';

$analyzer = new LogAnalyzer($logFile);
$analyzer->analyze();
