global php variables not saving after redirect

Question

I am using a custom module in drupal. where in a function I have used $GLOBALS['dataCapsue'] = array("some", "data", "here"); And then did a drupal_goto redirect to another url of my custom module. When i re declare global variable as global $dataCapsule; in another function. It returns NULL. What may be the cause of this issue. Am I missing something?

Thanks

Answer 1

Global variables are not persistent between http requests, like a redirect. You have to use a session to store this data between requests.

Answer 2

Use a $_SESSION variable or a browser cookie to get the stored data on the other site.
