PHP: Can I set Session Variables within Functions?

Question by Guest | 2014-06-30 at 11:02

In one of my PHP scripts, I would like to work with session variables ($_SESSION), also within functions.

Before starting to program this script, I would like to know, whether this is possible at all or if there are any objections for not doing so? So, can I normally work with session variables within functions or can this lead to any problems?

Such as setting a value within a function and having no access to this outside the function or vice versa or any other problems, for example.

$_SESSION is global and can be used everywhere, also within functions.

You only have to take care off always calling session_start() before setting or accessing any $_SESSION variable, otherwise it is not working.
