How can developers prevent exceeding the daily request limit for the Google Maps API in PHP?

To prevent exceeding the daily request limit for the Google Maps API in PHP, developers can implement caching mechanisms to store API responses locally and reuse them instead of making repeated requests to the API. This can help reduce the number of requests made to the API and stay within the daily limit. 

// Check if the API response is already cached
$cacheKey = 'google_maps_api_' . md5($requestParams);
$cacheFile = '/path/to/cache/' . $cacheKey;

if (file_exists($cacheFile) && time() - filemtime($cacheFile) < 86400) {
    // Use cached API response
    $apiResponse = file_get_contents($cacheFile);
} else {
    // Make API request
    $apiResponse = makeApiRequest($requestParams);

    // Cache the API response
    file_put_contents($cacheFile, $apiResponse);
}

// Function to make API request
function makeApiRequest($requestParams) {
    // Code to make API request
}
