Require() vs. $_SESSION[] Differences Advantages

[jsweet]

What are the differences and/or advantages to using Require() or $_SESSION[]? I'm new to PHP. Thanks in advance.

They are 2 totally different things. Not even remotely related.

SESSION variables are used to store information you may use during the stay of a user in your website. such as their login, or in the case of a shopping cart there selected items.

require() is used to bring a file with php commands, functions variables etc.. into the current one so its variables and code are available in the current script.

Entry for the Require function:

http://us.php.net/manual/en/function.require.php

Entry for the SESSION variable entry

http://us.php.net/manual/en/reserved.variables.session.php

The are used for different things. so really cannot be compared.

Ignorance is not necessarily Bliss, case in point:
Unknown has caused an Unknown Error on Unknown and must be shutdown to prevent damage to Unknown.

Since I've been doing this recently, I assume that you are looking into data filtering to secure your site. A quick search for that usually turns up the "Dispatch Method" (which uses sessions) and the "Include/Require Method". If that's what you're actually looking for, I have two suggestions.

One: word your questions better, this leads to better answers and less snark.

Two: read this -

oddly enough, the coding structure that I use most often is historically called the despatch method. I use sessions, but not for the despatching. For that, I pull in the appropriate scripts using require_once.

curious how the same terminology appears to be appropriated for subtly different purposes across the years!
