local variables of the same name as a session variable

[artie2004]

I have REGISTER_GLOBALS set to off and i have a local variable with the same name as a session variable. For example, i have a local variable $username and a session variable $_SESSION['username'] and when i assign the local variable $username a value, the session variable $_SESSION['username'] is also getting assigned this value. Does anyone know why this could be happening?

I'm still new at this but I am under the impression that _session acts like a memory bank to hold the information set into the variables values from one page to the next and to the DB if needed until u close the _session it will hold this information. I have a session on one page because I Want to carry the name from one to the next so i can place it in a specific place with out having to have the user fill out the form again.
Hope this makes sence

Are you using

session_register()

? That links a global variable to $_SESSION with behavior like you've described.

Kysmiley,

Yes, you are correct.

No. I am not using session_register(), because when using $_SESSION you don't need to use session_register() according to the PHP manual.

Does it happen with this minimal test case?

minimal.php

<? 
session_start(); 
echo $_SESSION['username'] . '<br>'; 
$username = 'foo'; 
echo $_SESSION['username']; 
?>

If not, I'd guess that you've got a

$username =& $_SESSION['username']

or

$_SESSION['username'] = $username

somewhere in your code.

Thanks for trying to help out you guys. It's my fault. I thought I had register_globals disabled but it wasn't. So, problem solved. Happy Holidays!
