Empty $_SESSION after PHP redirect using GET or CURL (not browser)

Error

Empty $_SESSION after PHP redirect between 2 scripts, the first script is called using GET or CURL (not browser)

Steps

1- Call "script1" using GET or CURL
2- "Script1" starts/fills session X, does some logic, redirect to "Script2"
3- In "Script2", print_r($_SESSION) is empty

Solution

I found that the SESSION in "Script2" is a NEW session, let's call it:Session Y , since Session X was not transferred in HTTP header in the redirect

So it seems that the SESSION information transfer in headers was being done by the browser and it is not done by GET or CURL command line, 

So we need to do it instead


Step 1:

In Script #1, change the redirection to be 

header("Location:$targetPage?".SID);

SID is a constant containing the following

PHPSESSID=oilq46ge4e2f76774qcg8gi3d1


Step 2:

In script #2, start the script with the following

session_id($_GET['PHPSESSID']);
session_start();

So you are telling the script to load Script1's session

That's it

Disney World app

Disney World Wait Time Lite: If you are lucky enough to go to Disney World soon, you'll need this app. It allows you access to real-time wait times for all the rides and also maps for all the parks. The times are updated constantly and will help you manage your time better. Very nice app. Here's the link. From the phone search for "disney world wait time lite" and install. And a personal advice: if you go to a park early, go to the rides at the back of the park. There's barely anyone there (people start with the closest rides). Your welcome!

File recovery app

Dumpster-Recycle bin: This can be a very useful app. It works just like the "recycle bin" on your computer. It allows you to recover deleted pictures with a single tap.
