Passing values use ENV variables

[Anon]

Hi,

I need to pass values to another page using environment variables.
The following code ....

$t = "xyz";
putenv("what=$t");
echo getenv("what");

actually writes "xyz" to the screen. However, if I go to another page than the one in which I did the putenv, the environment variable is gone.

Now, I need to pass a few values to another page using Environment variables.

Please let me know how to do this..

Thank you
