I was looking at the php docs on memcache and noticed that instead of doing
$mem->connect('localhost', 11211) I can do instead
$mem->addServer('localhost', 11211)
And this way if I don't end up using the memcache connection, it won't bother connecting.
This got me wondering, why would someone ever use connect() over addServer()?
It just seems like a possible unnecessary connection. Am I missing something?
