Session Variables from Functions

[vboctor]

Hi,

I have a function that I placed in a separate PHP file and I include it from within many other PHP files. I include this function using require_once and I do that after I call session_start (). However, I can not access the session variables from within the function. Do I need to call session start from within the function? Wouldn't this affect the caller, ie. it already modified session variables?

Regards,
Victor.

You need to send the variable to the function or use global.

session_start("mySessName");

// Now including and calling the function
include 'include/file.inc.php';
checkSessionName($mySessName);

(The function looks like)

function checkSessionName($mySessName)
{
}

if you want to return a new value to your session name use
$mySessName = checkSessionName($mySessName);

(function ends with : return($mySessName); )

global is easier (but less accurate)

include 'include/file.inc.php';
checkSessionName();

(The function looks like)
function checkSessionName()
{
global $mySessName;
// Change value over and over again is
// you want so.
}
