title: How to avoid Multi-user PHP Cache add up?
body: <p>I am developing a website using PHP and I want to store data on my user/browser's cache so I can keep the data through PHP pages without moving it all the time through <code>GET</code> or <code>POST</code>. I have used APC and APCu functions to make this work (Because I need the key-value system). </p>
  
  <p>However, I think I'm using the system cache (?) instead of the user's cache so when I try to run my program at multiple computers the cache of these users adds up. I would like this to be individual for each computer/user. I cannot find almost any APC/APCu functions whose parameters include the cache type of 'user' instead of 'system' (default) -- (like in <code>apc_clear_cache('user')</code> for example)</p>
  
  <p>Am I not using the right caching mechanism (APC, APCu, OPCache), am I missing parameters, or is it something else?</p>
