PHP Sessions – Understanding Growth

Hi, my name is Guillermo Antony Cava Nuñez, today we’ll dive into the confusing topic of PHP sessions. We understand that in order to make any sort of multi-user system function properly we need to store some piece of date from the user entering our system. However, if done incorrectly, we can either leave a gateway for bugs open, a problem for scaling to more users o simply a door for hackers wide open. We will cut the topic into 4 areas, the default [session_start()], redis, Memcached and database.
