Ability to control session-level variables through script

I’ve been able to embed some PHP scripts that pass data elements from one page to another, using hidden form fields, POST method, and _POST variables. I'm trying to figure out how to create and operate with **session-level variables** (_SESSION). For example, Sparkle could offer an option to insert session_start(); in the beginning of the generated PHP file to allow access to the session variables within the page through scripts. Without this, I cannot store and access these variables from various pages of the website. Instead, they are only accessible on the page that generated them (at global but not session level).

If there are other ways to accomplish this, I’d love to learn how. Thank you.

Sorry but again, we are focused on creating a visual editor for everybody. There are many tools that focus on coding, for coders.
