PHP Session Management

Session use

Before using the session in each page, you must use the Session_Start ()

You can use the $_session global array in each session, and the page must call Session_Start ()

The user's session on the site is unique, even if the page is called Session_Start ()

<? PHP Session_Start (); Echo session_id ()." <br> "; $_session ["added"]+=5; Echo $_session ["added"];? >
