Hi to all,
I have a problem. If session has a variable it create a php variable when i start session?

For example i call my code test.php?test=blabla
after this call session has testMe variable.
after this when i call just test.php there is $testMe php variable?

i think it is a php setting. how can i disable this settign?
Ps: php runs on linux
<?php
session_start();
if (isset($_GET["test"])){
	$_SESSION["testMe"]="Test string...";
	$testMe=$_SESSION["testMe"];
}
echo var_dump($_SESSION);
echo var_dump($testMe)
?>

If you set some session variable you can access it using the associative array  "$_SESSION". This session variable is a 'superglobal', or automatic global, variable. This means that it is available in all scopes throughout a script.  So  looks like the variable is "autoloaded" like a php local variable in the script.

To fix this issue, you have two options:

1 - Turn off the "Register Globals" directive editing the php.ini file
2 - Turn off the "Register Globals" with the .htaccess entry: php_flag register_globals off
3 - Use different names for the sessions variables and local variables.
