What are the potential pitfalls of making multiple API calls in a short period of time using PHP?

Making multiple API calls in a short period of time using PHP can lead to performance issues, such as increased server load and slower response times. To mitigate this, you can implement rate limiting by setting a delay between each API call to ensure that your application does not overwhelm the API server. 

// Set a delay between API calls to avoid overwhelming the server
$delay = 1; // Delay in seconds

$apiUrls = ['https://api.example.com/endpoint1', 'https://api.example.com/endpoint2', 'https://api.example.com/endpoint3'];

foreach ($apiUrls as $url) {
    $response = file_get_contents($url);
    
    // Process the API response
    
    // Add a delay before making the next API call
    sleep($delay);
}
