> Comece a usar o Firecrawl em PHP. Faça scraping, buscas e interaja com dados da web usando a API REST.

<div id="prerequisites">
  ## Pré-requisitos
</div>

* PHP 8.0+ com a extensão cURL
* Uma chave da API do Firecrawl — [obtenha uma grátis](https://www.firecrawl.dev/app/api-keys)

<div id="search-the-web">
  ## Fazer uma busca na web
</div>

O Firecrawl funciona com PHP por meio da API REST com cURL.

```php theme={null}
<?php
$apiKey = getenv('FIRECRAWL_API_KEY');

$ch = curl_init('https://api.firecrawl.dev/v2/search');
curl_setopt_array($ch, [
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POST => true,
    CURLOPT_HTTPHEADER => [
        'Authorization: Bearer ' . $apiKey,
        'Content-Type: application/json',
    ],
    CURLOPT_POSTFIELDS => json_encode([
        'query' => 'firecrawl web scraping',
        'limit' => 5,
    ]),
]);

$response = curl_exec($ch);
curl_close($ch);

$results = json_decode($response, true);
foreach ($results['data']['web'] as $result) {
    echo $result['title'] . ' - ' . $result['url'] . "\n";
}
```

<div id="reusable-helper-class">
  ## Classe auxiliar reutilizável
</div>

Para reutilização, encapsule a API em uma classe:

```php theme={null}
<?php
class Firecrawl
{
    private string $apiKey;
    private string $baseUrl = 'https://api.firecrawl.dev/v2';

    public function __construct(string $apiKey)
    {
        $this->apiKey = $apiKey;
    }

    private function post(string $endpoint, array $payload): array
    {
        $ch = curl_init($this->baseUrl . $endpoint);
        curl_setopt_array($ch, [
            CURLOPT_RETURNTRANSFER => true,
            CURLOPT_POST => true,
            CURLOPT_HTTPHEADER => [
                'Authorization: Bearer ' . $this->apiKey,
                'Content-Type: application/json',
            ],
            CURLOPT_POSTFIELDS => json_encode($payload),
        ]);

        $response = curl_exec($ch);
        $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
        curl_close($ch);

        if ($httpCode >= 400) {
            throw new \RuntimeException("Firecrawl API error: HTTP $httpCode");
        }

        return json_decode($response, true);
    }

    public function scrape(string $url, array $options = []): array
    {
        return $this->post('/scrape', array_merge(['url' => $url], $options));
    }

    public function search(string $query, int $limit = 5): array
    {
        return $this->post('/search', ['query' => $query, 'limit' => $limit]);
    }
}

// Uso
$app = new Firecrawl(getenv('FIRECRAWL_API_KEY'));
