Independent Private Sessions - php

Question

I need to manage multiple sessions in a website. I need to start a private sessions which is very page specific so it will terminate once I walk away from the page. But When I browse to previous page, i should be able to use my old session also. For example:
Page A -> Starts Session A
Page A -> is forwarded to Page B
Page B -> Start its own private Session B
Page B -> Completes the tasks and Terminates its private session B
Page B -> Redirects to Page A
Page A -> Again display the page using its old Session A
Can I start multiple sessions within a same website like this? If yes, How can I manage this?

Answer 1

You can use session_name for this, but if page B is killing its session as soon as a single page view is complete, it seems like a waste of time to use a session in the first place.

Answer 2

Perhaps something like;
$_SESSION[$_SERVER['PHP_SELF']]['name'] = $value;
//Page X termination
unset($_SESSION[$_SERVER['PHP_SELF']]);
Just tersely tossing out ideas here.
Expanding on the privatization of session data; A wrapper could help:
class Session implements ArrayAccess{
private $_data = array();
public function __construct(){
$this->_data = $_SESSION;
}
public function offsetSet($offset, $value){
$this->_data[$_SERVER['PHP_SELF']][$offset] = $value;
}
public function offsetExists($offset){
return isset($this->_data[$_SERVER['PHP_SELF']][$offset]);
}
public function offsetUnset($offset){
unset($this->_data[$_SERVER['PHP_SELF']][$offset]);
}
public function offsetGet($offset){
return isset($this->_data[$_SERVER['PHP_SELF']][$offset])
? $this->_data[$_SERVER['PHP_SELF']][$offset]
: null;
}
public function __destruct(){
$_SESSION = $this->_data;
}
}
$session = new Session;
//etc
Given the query string or more is relevant, you could hash the relevant values for the key.
Eg: $key = md5($_SERVER['PHP_SELF'] . $_SERVER['QUERY_STRING']); though using $_SERVER['REQUEST_URI'] as a key may suffice.
