PHP多執行緒程式設計實例：建立並發任務進行自然語言處理

class AnalysisThread extends Thread {
    private $paragraph;
    private $sentenceCount;
    private $wordCount;

    public function __construct($paragraph) {
        $this->paragraph = $paragraph;
        $this->sentenceCount = 0;
        $this->wordCount = 0;
    }

    public function run() {
        // 在这里进行自然语言处理的操作，比如使用分词库进行分词
        $this->sentenceCount = count($this->paragraph);
        $this->wordCount = count(explode(' ', $this->paragraph));
    }

    public function getSentenceCount() {
        return $this->sentenceCount;
    }

    public function getWordCount() {
        return $this->wordCount;
    }
}

// 假设$paragraphs是文章的段落数组
$threadPool = [];
foreach ($paragraphs as $paragraph) {
    $thread = new AnalysisThread($paragraph);
    $thread->start();
    $threadPool[] = $thread;
}

$totalSentenceCount = 0;
$totalWordCount = 0;

foreach ($threadPool as $thread) {
    $thread->join();
    $totalSentenceCount += $thread->getSentenceCount();
    $totalWordCount += $thread->getWordCount();
}

echo "文章中的句子数量：" . $totalSentenceCount . PHP_EOL;
echo "文章中的单词数量：" . $totalWordCount . PHP_EOL;
