Abraham - TwitterOAuth : Using with php cacher - php

Question

Before i make a call to twitter, I check for the chache version of data. If there is no cache, then i create a connection with twitter.
$connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, $access_token, $access_token);
This is how i have planned to do. I haven't started it yet.
The question is :
Which is best way to do this?
1) Check for the cache, if there is no cache create a new connection and get details from twitter.
2) Create a new connection in top of every file ( or in a header ) check for cache, if there is no cache, (connection is already exists. so) get the details from twitter.
And, How do i check whether the connection ($connection) is active?

Answer 1

The below would roughly do what you're asking for. The example below uses APC
//define cache key
$cacheKey = "twitterResponse[" . md5($endpoint, implode("&", $parameters) . "]";
//attempt to grab from cache
$foundCachedResponse = false;
$twitterResponse = apc_fetch($cacheKey, $foundCachedResponse);
//only when needed
if(!foundCachedResponse){
//twitter connection
$connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, $access_token, $access_token);
//make the call
$twitterResponse = $connection->getTweetsOrWhatever($parameters);
//cache the response
apc_store($cacheKey, $twitterResponse, 600);
}
//return
return $twitterResponse;
To see if APC is enabled:
if(!extension_loaded('apc')){
die('no APC');
}
