[Resolved] [Resolved] session confusion

Maiku

I don't quite understand sessions, so lets clear this up.

First of all, you session_start().

Then, you session_register(session).

Now, $session['variable'] = "whatever" will store information until the session ends, right?

How can I manage sessions over a number of pages? I assume put the session code in an included file, am I right?

Please help me. Thanks.

I don't know if you are familiar with cookies, but the concept is somewhat similar. Sessions are used to keep certain information between pages. You are correct that you need to call session_start() on every page that you want the session information. But the proper syntax for session_register is:


$var = "whatever";
session_register("var");

Depending on your version of PHP, session variables may be in the $_SESSION super-global.

These would be accessed like this:


$var = "whatever";
session_register("var");

echo $_SESSION[var];

This should print, "whatever."

Finally, using an include file can be a great idea, especially for large projects. Also, the more code you reuse, the faster you'll be able to complete projects.

Good luck. Have fun.

You should NOT use session_register() with the $_SESSION[] variable.

Just do $_SESSION['my_vars']='data';

And your script needs session_start() at the top.

When you go to the next page
$_SESSION['my_vars'] will already be set after the session_start().

You can pass arrays and variables the same way.

$arr = array( '1','2','3' );

$_SESSION['myarray']=$arr;

and it will be passed onto the next script when it is called.
