Call Array Value From Outside Function?

[Mink_]

I'm working on a web-RPG, and need a little help with my database queries, as I need to be setting up globals using unfctions.

I'm using this simple code that I came up with after a few minutes of looking at the PHP manual (I've already set the database up):

PHP Code:

function getuserinfo($id) {
    $query = mysql_query("SELECT * FROM users WHERE id = $id LIMIT 1");
    $user = mysql_fetch_array($query);
} 


Then, I want to call values from that by using things like $user['var'].
The only problem is, I can only seem to call values from that array inside the function, meaning that this will work:

PHP Code:

function getuserinfo($id) {
    $query = mysql_query("SELECT * FROM users WHERE id = $id LIMIT 1");
    $user = mysql_fetch_array($query);
    echo $user['var'];
}
getuserinfo(1); 


And this will not:

PHP Code:

function getuserinfo($id) {
    $query = mysql_query("SELECT * FROM users WHERE id = $id LIMIT 1");
    $user = mysql_fetch_array($query);
}
getuserinfo(1);
echo $user['var']; 


Is there an alternate way of getting the results I would see if the second bit of code worked? Or do I have to redesign my entire system?
