> Firecrawl PHP SDK 是对 Firecrawl API 的封装，可帮助你轻松将网站转换为 markdown。

<div id="installation">
  ## 安装
</div>

官方 PHP SDK 在 Firecrawl 的 monorepo 中维护，位于 [apps/php-sdk](https://github.com/firecrawl/firecrawl/tree/main/apps/php-sdk)。

要安装 Firecrawl PHP SDK，请通过 Composer 添加此依赖：

```bash theme={null}
composer require firecrawl/firecrawl-sdk
```

<Note>需要 PHP 8.1 或更高版本。</Note>

<div id="laravel-integration">
  ### Laravel 集成
</div>

该 SDK 提供对 Laravel 的原生支持，并支持自动发现。安装该软件包后，请发布配置文件：

```bash theme={null}
php artisan vendor:publish --provider="Firecrawl\Laravel\FirecrawlServiceProvider"
```

然后将你的 API 密钥添加到 `.env` 文件中：

```env theme={null}
FIRECRAWL_API_KEY=fc-your-api-key
```

支持以下环境变量：

| 变量                         | 默认值                         | 描述                       |
| -------------------------- | --------------------------- | ------------------------ |
| `FIRECRAWL_API_KEY`        | —                           | 你的 Firecrawl API 密钥 (必填) |
| `FIRECRAWL_API_URL`        | `https://api.firecrawl.dev` | API 基础 URL               |
| `FIRECRAWL_TIMEOUT`        | `300`                       | HTTP 请求超时时间 (秒)          |
| `FIRECRAWL_MAX_RETRIES`    | `3`                         | 临时故障时的自动重试次数             |
| `FIRECRAWL_BACKOFF_FACTOR` | `0.5`                       | 指数退避系数 (秒)               |

<div id="usage">
  ## 使用方式
</div>

1. 从 [firecrawl.dev](https://firecrawl.dev) 获取 API 密钥
2. 将 API 密钥设置为名为 `FIRECRAWL_API_KEY` 的环境变量，或通过 `FirecrawlClient::create(apiKey: ...)` 传入 API 密钥

以下是一个基于当前 SDK API 的简要示例：

```php theme={null}
use Firecrawl\Client\FirecrawlClient;
use Firecrawl\Models\CrawlOptions;
use Firecrawl\Models\ScrapeOptions;

$client = FirecrawlClient::fromEnv();

$doc = $client->scrape(
    'https://firecrawl.dev',
    ScrapeOptions::with(formats: ['markdown'])
);

$crawl = $client->crawl(
    'https://firecrawl.dev',
    CrawlOptions::with(limit: 5)
);

echo $doc->getMarkdown();
echo 'Crawled pages: ' . count($crawl->getData());
```

<div id="using-the-laravel-facade">
  ### 使用 Laravel 门面
</div>

在 Laravel 应用中，可以使用 `Firecrawl` 门面，或通过依赖注入：

```php theme={null}
use Firecrawl\Client\FirecrawlClient;
use Firecrawl\Laravel\Facades\Firecrawl;

// 通过 Facade
$doc = Firecrawl::scrape('https://example.com');

// 通过依赖注入
class ScrapeController
{
    public function __construct(
        private readonly FirecrawlClient $firecrawl,
    ) {}

    public function index()
    {
        $doc = $this->firecrawl->scrape('https://example.com');
        return response()->json(['markdown' => $doc->getMarkdown()]);
    }
}
```

<div id="scraping-a-url">
  ### 抓取 URL
</div>

如需抓取单个 URL，请使用 `scrape` 方法。

```php theme={null}
use Firecrawl\Models\Document;
use Firecrawl\Models\ScrapeOptions;

$doc = $client->scrape(
    'https://firecrawl.dev',
    ScrapeOptions::with(
        formats: ['markdown', 'html'],
        onlyMainContent: true,
        waitFor: 5000,
    )
);

echo $doc->getMarkdown();
echo $doc->getMetadata()['title'] ?? '';
```

<div id="json-extraction">
  #### JSON 提取
</div>

通过 `scrape` 端点，使用 `JsonFormat` 提取结构化 JSON：

```php theme={null}
use Firecrawl\Models\JsonFormat;
use Firecrawl\Models\ScrapeOptions;

$jsonFmt = JsonFormat::with(
    prompt: 'Extract the product name and price',
    schema: [
        'type' => 'object',
        'properties' => [
            'name' => ['type' => 'string'],
            'price' => ['type' => 'number'],
        ],
    ],
);

$doc = $client->scrape(
    'https://example.com/product',
    ScrapeOptions::with(formats: [$jsonFmt])
);

print_r($doc->getJson());
```

<div id="crawling-a-website">
  ### 爬取网站
</div>

要爬取网站并等待其完成，请使用 `crawl`。

```php theme={null}
use Firecrawl\Models\CrawlOptions;
use Firecrawl\Models\ScrapeOptions;

$job = $client->crawl(
    'https://firecrawl.dev',
    CrawlOptions::with(
        limit: 50,
        maxDiscoveryDepth: 3,
        scrapeOptions: ScrapeOptions::with(formats: ['markdown']),
    )
);

echo 'Status: ' . $job->getStatus();
echo 'Progress: ' . $job->getCompleted() . '/' . $job->getTotal();

foreach ($job->getData() as $page) {
    echo $page->getMetadata()['sourceURL'] ?? '';
}
```

<div id="start-a-crawl">
  ### 开始爬取
</div>

使用 `startCrawl` 启动任务，无需等待。

```php theme={null}
use Firecrawl\Models\CrawlOptions;

$start = $client->startCrawl(
    'https://firecrawl.dev',
    CrawlOptions::with(limit: 100)
);

echo 'Job ID: ' . $start->getId();
```

<div id="checking-crawl-status">
  ### 查看爬取状态
</div>

使用 `getCrawlStatus` 查看爬取进度。

```php theme={null}
$status = $client->getCrawlStatus($start->getId());
echo 'Status: ' . $status->getStatus();
echo 'Progress: ' . $status->getCompleted() . '/' . $status->getTotal();
```

<div id="cancelling-a-crawl">
  ### 取消爬取
</div>

使用 `cancelCrawl` 取消正在进行中的爬取。

```php theme={null}
$result = $client->cancelCrawl($start->getId());
print_r($result);
```

<div id="crawl-errors">
  ### 爬取错误
</div>

使用 `getCrawlErrors` 获取爬取过程中的错误 (如有) 。

```php theme={null}
$errors = $client->getCrawlErrors($start->getId());
print_r($errors);
```

<div id="mapping-a-website">
  ### 网站映射
</div>

使用 `map` 发现网站中的链接。

```php theme={null}
use Firecrawl\Models\MapOptions;

$data = $client->map(
    'https://firecrawl.dev',
    MapOptions::with(
        limit: 100,
        search: 'blog',
    )
);

foreach ($data->getLinks() as $link) {
    echo ($link['url'] ?? '') . ' - ' . ($link['title'] ?? '');
}
```

<div id="searching-the-web">
  ### 搜索网页
</div>

使用 `search` 并可选配搜索设置进行搜索。

```php theme={null}
use Firecrawl\Models\SearchOptions;

$results = $client->search(
    'firecrawl web scraping',
    SearchOptions::with(limit: 10)
);

foreach ($results->getWeb() as $result) {
    echo ($result['title'] ?? '') . ' - ' . ($result['url'] ?? '');
}
```

<div id="batch-scraping">
  ### 批量抓取
</div>

使用 `batchScrape` 并行抓取多个 URL。

```php theme={null}
use Firecrawl\Models\BatchScrapeOptions;
use Firecrawl\Models\ScrapeOptions;

$job = $client->batchScrape(
    ['https://firecrawl.dev', 'https://firecrawl.dev/blog'],
    BatchScrapeOptions::with(
        options: ScrapeOptions::with(formats: ['markdown']),
    )
);

foreach ($job->getData() as $doc) {
    echo $doc->getMarkdown();
}
```

如需手动控制异步流程，请使用 `startBatchScrape`、`getBatchScrapeStatus` 和 `cancelBatchScrape`：

```php theme={null}
use Firecrawl\Models\BatchScrapeOptions;
use Firecrawl\Models\ScrapeOptions;

$start = $client->startBatchScrape(
    ['https://firecrawl.dev', 'https://firecrawl.dev/blog'],
    BatchScrapeOptions::with(
        options: ScrapeOptions::with(formats: ['markdown']),
    )
);

$status = $client->getBatchScrapeStatus($start->getId());
echo 'Batch status: ' . $status->getStatus();

$cancel = $client->cancelBatchScrape($start->getId());
print_r($cancel);
```

<div id="agent">
  ### 代理
</div>

使用 `agent` 运行 AI 代理。

```php theme={null}
use Firecrawl\Models\AgentOptions;

$result = $client->agent(
    AgentOptions::with(
        prompt: 'Find the pricing plans for Firecrawl and compare them',
    )
);

print_r($result->getData());
```

使用结构化输出的 JSON schema：

```php theme={null}
use Firecrawl\Models\AgentOptions;

$result = $client->agent(
    AgentOptions::with(
        prompt: 'Extract pricing plan details',
        urls: ['https://firecrawl.dev'],
        schema: [
            'type' => 'object',
            'properties' => [
                'plans' => [
                    'type' => 'array',
                    'items' => [
                        'type' => 'object',
                        'properties' => [
                            'name' => ['type' => 'string'],
                            'price' => ['type' => 'string'],
                        ],
                    ],
                ],
            ],
        ],
    )
);

print_r($result->getData());
```

如需手动控制异步执行，请使用 `startAgent`、`getAgentStatus` 和 `cancelAgent`：

```php theme={null}
use Firecrawl\Models\AgentOptions;

$start = $client->startAgent(
    AgentOptions::with(
        prompt: 'Summarize what Firecrawl does in one sentence',
        urls: ['https://firecrawl.dev'],
    )
);

$status = $client->getAgentStatus($start->getId());
echo 'Agent status: ' . $status->getStatus();

$cancel = $client->cancelAgent($start->getId());
print_r($cancel);
```

<div id="usage-metrics">
  ### 使用方式与指标
</div>

查看并发数和剩余额度：

```php theme={null}
use Firecrawl\Models\ConcurrencyCheck;
use Firecrawl\Models\CreditUsage;

$concurrency = $client->getConcurrency();
echo 'Concurrency: ' . $concurrency->getConcurrency() . '/' . $concurrency->getMaxConcurrency();

$credits = $client->getCreditUsage();
echo 'Remaining credits: ' . $credits->getRemainingCredits();
```

<div id="browser">
  ## 浏览器
</div>

PHP SDK 提供了 浏览器 Sandbox 辅助函数。

<div id="create-a-session">
  ### 创建会话
</div>

```php theme={null}
use Firecrawl\Models\BrowserCreateResponse;

$session = $client->browser(ttl: 120, activityTtl: 60, streamWebView: true);
echo $session->getId();
echo $session->getCdpUrl();
echo $session->getLiveViewUrl();
```

<div id="execute-code">
  ### 执行代码
</div>

```php theme={null}
use Firecrawl\Models\BrowserExecuteResponse;

$run = $client->browserExecute(
    sessionId: $session->getId(),
    code: 'await page.goto("https://example.com"); console.log(await page.title());',
    language: 'node',
    timeout: 60,
);

echo $run->getStdout();
echo $run->getExitCode();
```

<div id="scrape-bound-interactive-session">
  ### 与抓取任务绑定的交互式会话
</div>

使用抓取任务 ID，在同一重放上下文中运行后续浏览器代码：

* `interact(...)` 会在与抓取任务绑定的浏览器会话中运行代码 (首次使用时会自动初始化该会话) 。
* `stopInteractiveBrowser(...)` 会在你使用完毕后显式停止该交互式会话。

```php theme={null}
use Firecrawl\Models\BrowserExecuteResponse;
use Firecrawl\Models\BrowserDeleteResponse;
use Firecrawl\Models\ScrapeOptions;

$doc = $client->scrape(
    'https://example.com',
    ScrapeOptions::with(formats: ['markdown'])
);

$scrapeJobId = $doc->getMetadata()['scrapeId'] ?? null;
if ($scrapeJobId === null) {
    throw new RuntimeException('scrapeId not found in metadata');
}

$scrapeRun = $client->interact(
    jobId: $scrapeJobId,
    code: 'console.log(page.url());',
    language: 'node',
    timeout: 60,
);

echo $scrapeRun->getStdout();

$deleted = $client->stopInteractiveBrowser($scrapeJobId);
echo 'Deleted: ' . ($deleted->isSuccess() ? 'true' : 'false');
```

<div id="list-close-sessions">
  ### 列出并关闭会话
</div>

```php theme={null}
use Firecrawl\Models\BrowserListResponse;
use Firecrawl\Models\BrowserSession;

$active = $client->listBrowsers('active');
foreach ($active->getSessions() as $s) {
    echo $s->getId() . ' - ' . $s->getStatus();
}

$closed = $client->deleteBrowser($session->getId());
echo 'Closed: ' . ($closed->isSuccess() ? 'true' : 'false');
```

<div id="configuration">
  ## 配置
</div>

`FirecrawlClient::create()` 支持以下选项：

| 选项               | 类型                           | 默认值                                                 | 描述                      |
| ---------------- | ---------------------------- | --------------------------------------------------- | ----------------------- |
| `apiKey`         | `string`                     | `FIRECRAWL_API_KEY` 环境变量                            | 你的 Firecrawl API 密钥     |
| `apiUrl`         | `string`                     | `https://api.firecrawl.dev` (或 `FIRECRAWL_API_URL`) | API 基础 URL              |
| `timeoutSeconds` | `float`                      | `300`                                               | HTTP 请求超时时间 (秒)         |
| `maxRetries`     | `int`                        | `3`                                                 | 发生临时故障时自动重试             |
| `backoffFactor`  | `float`                      | `0.5`                                               | 指数退避系数 (秒)              |
| `httpClient`     | `GuzzleHttp\ClientInterface` | 根据 timeout 构建                                       | 自定义的 Guzzle 兼容 HTTP 客户端 |

```php theme={null}
use Firecrawl\Client\FirecrawlClient;

$client = FirecrawlClient::create(
    apiKey: 'fc-your-api-key',
    apiUrl: 'https://api.firecrawl.dev',
    timeoutSeconds: 300,
    maxRetries: 3,
    backoffFactor: 0.5,
);
```

<div id="custom-http-client">
  ### 自定义 HTTP 客户端
</div>

你可以传入一个预先配置的 `GuzzleHttp\ClientInterface` 实现，用于控制连接池、中间件、代理设置及其他 HTTP 功能。提供该实现后，`timeoutSeconds` 设置将被忽略，改为以客户端自身的配置为准。

```php theme={null}
use Firecrawl\Client\FirecrawlClient;
use GuzzleHttp\Client as GuzzleClient;

$guzzle = new GuzzleClient([
    'proxy' => 'http://proxy.example.com:8080',
    'timeout' => 60,
    'connect_timeout' => 10,
]);

$client = FirecrawlClient::create(
    apiKey: 'fc-your-api-key',
    httpClient: $guzzle,
);
```

<div id="error-handling">
  ## 错误处理
</div>

SDK 会抛出位于 `Firecrawl\Exceptions` 命名空间下的运行时异常。

```php theme={null}
use Firecrawl\Exceptions\AuthenticationException;
use Firecrawl\Exceptions\FirecrawlException;
use Firecrawl\Exceptions\JobTimeoutException;
use Firecrawl\Exceptions\RateLimitException;

try {
    $doc = $client->scrape('https://example.com');
} catch (AuthenticationException $e) {
    echo 'Auth failed: ' . $e->getMessage();
} catch (RateLimitException $e) {
    echo 'Rate limited: ' . $e->getMessage();
} catch (JobTimeoutException $e) {
    echo 'Job ' . $e->getJobId() . ' timed out after ' . $e->getTimeoutSeconds() . 's';
} catch (FirecrawlException $e) {
    echo 'Error ' . $e->getStatusCode() . ': ' . $e->getMessage();
}
```
