As you should be aware the HTTP protocol, as used for serving web pages, is completely stateless.There are many reasons why you can get foreign key errors, and often very different reasons give the same error, which is why it's sometimes so hard to track down exactly what is the cause.The purpose of this white paper is to create an exhaustive list of the reasons why you get these error, and then to expand on that list with other things that can go wrong when trying to create foreign keys.

By default the medium used as persistent storage by the session handler will be a series of disk files, one per session, where the file name is the session_id.
A file is created when a new session starts, and is deleted when the session terminates (or has expired).
Fortunately PHP provides a standard method of maintaining memory (state) between requests in the form of Session Handling functions.
This allows the programmer to maintain a set of variables in the $_SESSION array which is automatically saved to persistent storage at the end of each script, and then automatically loaded back into memory when a subsequent request is received from a client which supplies the same session_id.
