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;
}
}
最佳实践建议
- 错误处理：实现完善的异常处理和重试机制
- 日志记录：记录完整的翻译流程便于调试
- 性能优化：使用缓存和异步处理提高效率
- 安全性：保护API密钥，处理用户输入安全
- 扩展性：设计模块化，便于添加新翻译服务
这个工作流设计可以灵活满足不同场景的翻译需求,你可以根据具体项目需求进行调整。
