고성능 실시간 로그 분석을 위해 PHP와 Swoole을 사용하는 방법은 무엇입니까?

$ 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();
