why is my once working code saying its deprecated?

[linkenpark51471]

my login page once worked but all of a sudden today stopped working and no one on my site could login to there accounts then a little later in the day i got an error saying
"Deprecated: Function session_register() is deprecated in on line"

Could be to do with the 'Litespeed' server upgrade as part of the process would logically include an upgrade to the latest PHP version. It appears your code relies upon functions that are no longer being supported.

see: http://php.net/manual/en/function.session-register.php

its the session_register one. so for example it was
session_register("shares");

what would i change it to?
