was looking for a rather comprehensive list of modules, and found http://stackoverflow.com/questions/8415962/what-exactly-phps-function-session-module-name-is-for but there are more.

This function is used to set the Session Module at site or script level.
The global configuration can be done in php.ini under the [Session] section and with the name of "session.save_handler". The sessions are saved in files by default, like so:
session.save_handler = files
But with this configuration you set one of your websites to use some other session module (if you have them installed and extension loaded with PHP), like so:
<?php
// NOTE: You must use this function before starting session with session_start(); to make it work properly
session_module_name('memcache'); // or pgsql or redis etc
// You'll need to define a save path also, if the module is other than files, like so:
session_save_path('localhost:11211'); // memcache uses port 11211
// or you can use multiple for load balancing:
session_save_path('localhost:11211:41,otherhost:11211:60') // First part is hostname or path to socket, next is port and the last is the weight for that server
//The function also returns the value of the current session module.
echo session_module_name(); // will print memcache in our case
// or maybe a check
if(session_module_name() != 'memcache'){
// Do something, throw an exception maybe
}

<?php
session_start();
$_SESSION['name']="Tushar";
$n=$_SESSION['name'];
$_SESSION['Age']="23";
$_SESSION['city']="Tarapur";
//echo session_encode()."<br/>";//Prints all Session Data
//echo session_is_registered($n);
echo session_module_name();//it prints "files"
?>
output:
files
