PHP Session does not work

[Octavio]

It often see problems with sessions in PHP. Here is an example of error:

<? php 
if (isset ($ _SESSION [ 'test'])) 
( 
/ / action 
) 
>

Troubleshooting:

Here we see that the direction session_start (); was forgotten. We must therefore add:

<? php 
session_start (); 
if (isset ($ _SESSION [ 'test'])) 
( 
/ / action 
) 
>

Once this is done, it is possible that the problem persists. How in this case?

• Make sure you do not send HTML (between PHP tags or not) before session_start (); an echo''as HTML output is the same thing).
  
• Make sure you do wrong in the name of your variable, $ _SESSION and $ _SESSION are two different tables (only one being correct in our use).
  
• Check for certain hosts that you have created a directory suitable for the sessions (eg at Free must create a session at the root of your FTP account.
