我来帮你梳理PHP翻译工作流的实现方案：

基础翻译工作流结构

<?php
class TranslationWorkflow {
    private $sourceLang;
    private $targetLang;
    private $translator;
    private $cache;
    public function __construct($sourceLang, $targetLang) {
        $this->sourceLang = $sourceLang;
        $this->targetLang = $targetLang;
        $this->cache = new CacheManager();
    }
    public function translateContent($content) {
        // 1. 检查缓存
        $cacheKey = md5($content . $this->sourceLang . $this->targetLang);
        if ($cached = $this->cache->get($cacheKey)) {
            return $cached;
        }
        // 2. 执行翻译
        $translated = $this->performTranslation($content);
        // 3. 保存缓存
        $this->cache->set($cacheKey, $translated);
        return $translated;
    }
}

翻译服务集成

<?php
class TranslationService {
    // Google Translate API
    public function googleTranslate($text, $targetLang) {
        $apiKey = 'YOUR_API_KEY';
        $url = "https://translation.googleapis.com/language/translate/v2";
        $data = [
            'q' => $text,
            'target' => $targetLang,
            'format' => 'text',
            'key' => $apiKey
        ];
        $ch = curl_init($url);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, [
            'Content-Type: application/json'
        ]);
        $response = curl_exec($ch);
        curl_close($ch);
        $result = json_decode($response, true);
        return $result['data']['translations'][0]['translatedText'];
    }
    // DeepL API
    public function deepLTranslate($text, $targetLang) {
        $apiKey = 'YOUR_API_KEY';
        $url = "https://api-free.deepl.com/v2/translate";
        $data = [
            'text' => $text,
            'target_lang' => $targetLang,
            'auth_key' => $apiKey
        ];
        $ch = curl_init($url);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        $response = curl_exec($ch);
        curl_close($ch);
        $result = json_decode($response, true);
        return $result['translations'][0]['text'];
    }
}

内容提取与分段

<?php
class ContentExtractor {
    public function extractTextSegments($html) {
        $segments = [];
        // 使用DOMDocument解析HTML
        $dom = new DOMDocument();
        @$dom->loadHTML(mb_convert_encoding($html, 'HTML-ENTITIES', 'UTF-8'));
        // 提取文本节点
        $xpath = new DOMXPath($dom);
        $textNodes = $xpath->query('//text()[normalize-space()]');
        foreach ($textNodes as $node) {
            $text = trim($node->nodeValue);
            if (!empty($text) && $this->shouldTranslate($text)) {
                $segments[] = [
                    'node' => $node,
                    'text' => $text
                ];
            }
        }
        return $segments;
    }
    private function shouldTranslate($text) {
        // 检查是否包含需要翻译的内容
        // 排除URL、代码、变量等
        if (preg_match('/^(https?:\/\/|www\.)/', $text)) return false;
        if (preg_match('/^[0-9\s,.]+$/', $text)) return false;
        if (strlen($text) < 2) return false;
        return true;
    }
}

批量处理工作流

<?php
class BatchTranslationWorkflow {
    private $sourceLanguage;
    private $targetLanguage;
    private $queue = [];
    private $results = [];
    public function processBatch($items) {
        $chunks = array_chunk($items, 10); // 每批10个
        foreach ($chunks as $chunk) {
            $this->processChunk($chunk);
        }
        return $this->results;
    }
    private function processChunk($chunk) {
        $promises = [];
        foreach ($chunk as $item) {
            $promises[] = $this->translateAsync($item);
        }
        // 等待所有异步请求完成
        $this->results = array_merge($this->results, $promises);
    }
    private function translateAsync($item) {
        // 实现异步翻译
        $translation = $this->translateItem($item);
        return [
            'source' => $item,
            'translation' => $translation,
            'status' => 'success',
            'timestamp' => time()
        ];
    }
}

翻译质量控制

<?php
class QualityControl {
    public function validateTranslation($source, $translated) {
        $checks = [
            $this->checkLength($source, $translated),
            $this->checkFormatting($translated),
            $this->checkSpecialCharacters($translated),
            $this->checkCodeBlocks($translated)
        ];
        return in_array(false, $checks) ? false : true;
    }
    private function checkLength($source, $translated) {
        // 检查长度差异是否在接受范围内
        $sourceLen = strlen($source);
        $translatedLen = strlen($translated);
        return abs($sourceLen - $translatedLen) / $sourceLen < 0.5;
    }
    private function checkFormatting($text) {
        // 检查是否保留了必要的格式
        return true;
    }
}

工作流管理

<?php
class TranslationWorkflowManager {
    private $steps = [
        'extract',      // 提取内容
        'prepare',      // 准备翻译
        'translate',    // 执行翻译
        'validate',     // 质量检查
        'merge'         // 合并结果
    ];
    public function execute($content, $options = []) {
        $currentContent = $content;
        foreach ($this->steps as $step) {
            $currentContent = $this->executeStep($step, $currentContent, $options);
            // 记录日志
            $this->logStep($step, $currentContent);
        }
        return $currentContent;
    }
    private function executeStep($step, $content, $options) {
        switch ($step) {
            case 'extract':
                return $this->extractContent($content);
            case 'prepare':
                return $this->prepareContent($content);
            case 'translate':
                return $this->translateContent($content, $options);
            case 'validate':
                return $this->validateContent($content);
            case 'merge':
                return $this->mergeContent($content);
        }
    }
}

使用示例

<?php
// 初始化工作流
$workflow = new TranslationWorkflow('en', 'zh-CN');
// 翻译单个文本
$text = "Hello, World!";
$translation = $workflow->translateContent($text);
echo "翻译结果: " . $translation;
// 翻译HTML内容
$html = '<p>欢迎访问我们的网站</p>';
$translatedHtml = $workflow->translateContent($html);
// 批量翻译
$items = [
    'Good morning',
    'How are you?',
    'Thank you'
];
$workflow = new BatchTranslationWorkflow('en', 'zh-CN');
$results = $workflow->processBatch($items);
// 高级：带质量检查
$manager = new TranslationWorkflowManager();
$translated = $manager->execute($html, [
    'source_lang' => 'en',
    'target_lang' => 'zh-CN',
    'quality_check' => true
]);

配置管理

<?php
class TranslationConfig {
    private $config = [
        'cache_enabled' => true,
        'cache_ttl' => 3600,
        'batch_size' => 10,
        'max_retries' => 3,
        'timeout' => 30,
        'service' => 'google',  // google, deepl, microsoft
        'api_keys' => [
            'google' => 'YOUR_GOOGLE_API_KEY',
            'deepl' => 'YOUR_DEEPL_API_KEY'
        ]
    ];
    public function get($key) {
        return isset($this->config[$key]) ? $this->config[$key] : null;
    }
    public function set($key, $value) {
        $this->config[$key] = $value;
    }
}
