A simple PHP Class to update Google AMP Cache
composer require ennexa/amp-update-cache:dev-master
To purge the cache for https://www.prokerala.com/health/?amp=1
$var = new Ennexa\AmpCache\Update(PATH_TO_YOUR_PRIVATE_KEY); // Make sure your private key is outside document root
$status = $var->purge('https://www.prokerala.com/health/?amp=1');
The script will purge the cache url from all the caches listed in AMP Project's official caches list.
If you want to purge only Google's AMP cache, you can filter the list as below
$updater = new Ennexa\AmpCache\Update(PATH_TO_YOUR_PRIVATE_KEY);
$updater->setCache(array_filter($updater->getCache(), function($cache) {
return 'google' === $cache->id;
}));
$status = $updater->purge('https://www.prokerala.com/health/?amp=1');
