How can browser caching impact the retrieval of live data from APIs in PHP applications?

Browser caching can impact the retrieval of live data from APIs in PHP applications by serving cached responses instead of fetching the latest data from the API. To solve this issue, you can add cache control headers to the API response to instruct the browser not to cache the data. 

// Set cache control headers to prevent browser caching
header("Cache-Control: no-cache, no-store, must-revalidate");
header("Pragma: no-cache");
header("Expires: 0");
