Can anybody tell me how to cache a dynamically generated page for some time using php. Home page of my site involve certain dynamic contents but remains constant for some time. So rather than using database for all requests it would be better if i could serve the client from the cache. Please help.

Hi,

First you need to install memcache API.

you can store db values to cached once then you can get the values from cache every time using this memcache class.

you can delete the memcached values by expiry time or while any db value changes.

If your page is dynamic, you should delete the memcache when you change db values related that dynamic pages

eg:

$oMemCache = new Memcache;
$oMemCache -> addServer('host', portnumber);

if($oMemCache->get('your_memcached_key'))
{
print $oMemCache->get('your_memcached_key');
}
else
{

//#--- Get your db result & then stored into memcache key
$vDBValue = from sql result;
$oMemCache->set('your_memcached_key', $vDBValue);

}
