How to concatenate session value

[Manan]

Hello All

 

I am generating new session value every time when page is reload. I am getting session result like this:

compare_session_281,147,136 ⇒ 281,147,136
compare_session_96,46,30 ⇒ 96,46,30
compare_session_29,27,26 ⇒ 29,27,26

compare_session_281,147,136, compare_session_96,46,30 and compare_session_29,27,26 are my sessions.

 

Now I want to concate session value like this:

compare_session = 281,147,136,96,46,30,29,27,26

Any ideas or suggestion?

 

Thanks

For the benefit of the non-clairvoyant ones out here, what's your current code for creating the session variables?
