Is there anyway to make a session variable global?

wizhippo

I want to be able to access $_SESSION['varname'] as $varname without registerglobals on.

So do a
$varname = $_SESSION['varname'];

If you want to make all of them global, just use a foreach loop

foreach ($_SESSION as $varname=>$value) {
$$varname = $value;
}

I've tried but does it work for globals?

eg.

global $foo;
$foo = $_SESSION['foo'];

when i do a

$foo['val'] = 'val';

$_SESSION['foo'] is not updated.

Well, they are not the SAME variable. They have the same value, because it was copied to it, but it's just a copy, not the real one.

You want references.

I have previously read the refernces and it looks like you can't do it because both $_SESSION['var'] and global var(same thing as $GLOBALS['var']) are referneces and you can't assign a refference to a reffernce.

If you know how to do this an give an example i would owe you big time!

This works for me:

<?php
$_SESSION['one'] = 1;
$two = &$_SESSION['one'];
$two = 2;
print $_SESSION['one'];  // prints 2
?>

try make two global it won't work

get a parse error

<?php

$user = array();

function foo() {
global $user;

$user = &$_SESSION['user'];

}

foo();

$user['name'] = 'fred'; // Does not update $_SESSION['user']

the above is what i'm tryin to do but to no avail.

any hints or ideas

below is code that works to make a global the same as a session variable

// get user info array
if(!isset($_SESSION['mjUser'])) {
	$mjUser = array();
	$_SESSION['mjUser'] =& $mjUser;
}
else {
	$mjUser = $_SESSION['mjUser'];;
	$_SESSION['mjUser'] =& $mjUser;
}
