title: Reusing a PDO connection after execute?
body: <p>I would like to know if it's correct to re-use a PDO db connection multiple times ?</p>
  
  <p>For example, I set it up in my controller then pass it as a parameter in a constructor of a class, is it correct to call the same connection (by using a function like get_Database) thoughout all my functions in the class and even pass it as a parameter in another class construct to continue working with the same connection ?</p>
  
  <p>Or should I reopen a connection at some point ?</p>
  
  <p>I was able to get it working by simply passing it around, however I am not quite sure if this would be performing well when going live.</p>
