What are the best practices for handling API limits and pagination when creating multiple files in PHP?

When creating multiple files using an API in PHP, it's important to handle API limits and pagination properly to avoid hitting rate limits or missing data. One way to do this is by making sure to check the API response for pagination information and making subsequent requests to fetch all the necessary data. Additionally, you can implement a delay between API requests to avoid exceeding rate limits.

// Example code snippet for handling API limits and pagination when creating multiple files in PHP

$apiEndpoint = 'https://api.example.com/data';
$perPage = 100;
$page = 1;
$allData = [];

do {
    $response = file_get_contents($apiEndpoint . '?page=' . $page . '&per_page=' . $perPage);
    $data = json_decode($response, true);
    
    if (!empty($data)) {
        $allData = array_merge($allData, $data);
        $page++;
    }
    
    // Add a delay between API requests to avoid hitting rate limits
    sleep(1);
    
} while (!empty($data));

// Process the $allData array containing all the fetched data
