How can developers efficiently handle bulk data retrieval from external APIs in PHP without violating usage limits or getting blocked?

To efficiently handle bulk data retrieval from external APIs in PHP without violating usage limits or getting blocked, developers can implement rate limiting and pagination techniques. By setting a limit on the number of requests made within a specific time frame and fetching data in smaller chunks using pagination, developers can prevent overwhelming the API and ensure smooth data retrieval. 

// Example code snippet implementing rate limiting and pagination for bulk data retrieval from an external API

$apiUrl = 'https://api.example.com/data';
$perPage = 100;
$totalPages = 10;
$apiKey = 'your_api_key_here';

for ($page = 1; $page <= $totalPages; $page++) {
    $response = file_get_contents($apiUrl . '?page=' . $page . '&perPage=' . $perPage . '&apiKey=' . $apiKey);
    
    // Process the API response here
    
    // Implement rate limiting to prevent exceeding usage limits
    sleep(1); // Wait for 1 second before making the next request
}
