<div id="search-the-web">
  ## Buscar en la web [#buscar-en-la-web]

Firecrawl funciona con PHP a través de la API REST utilizando cURL.

```php
<?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";
}
```
