Initiate a new session and send the cookie data for it
Description
This function will start a new session and clear any existing session information. This generates a random session ID and passes it as a cookie back to the browser, so it needs to be called before any other data is sent out. You can then set session variables through the global $_SESSION array.
This is only applicable for HTTP initiated scripts. The $_SESSION array is available to all HTTP scripts to allow for persistent variables to be shared between scripts. This array is associated with the script based on the cookie created.
Parameters
None
Return Values
None
