How can APIs be used to extract data from websites in PHP?

To extract data from websites in PHP, APIs can be used to access the data in a structured way. By using APIs provided by websites, developers can retrieve specific data without having to scrape the website's HTML directly. This allows for more reliable and efficient data extraction. 

// Example code to extract data from a website using an API in PHP
$api_url = 'https://api.example.com/data'; // API endpoint URL
$api_key = 'your_api_key_here'; // API key for authentication

// Make a request to the API using cURL
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $api_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Authorization: Bearer ' . $api_key
));

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

// Process the API response
$data = json_decode($response, true);

// Extract and use the desired data
foreach ($data['results'] as $result) {
    echo $result['name'] . ': ' . $result['value'] . '<br>';
}
