Explode (); Problem *Solved

Hello, Heres my class with all my functions:

[CODE]
<?php
session_start();

error_reporting(E_ALL);

mysql_close($this->connection);

}

function check_user() {
 
    if (!isset($_SESSION['userinfo'])) {
 
      $this->login_box();

function logout() {

[/CODE]

Alright so with the function check_user(); it doesnt explode the session properly. The variables $user and $pass are empty.

Whats wrong with it?

The whole code is there so you should be able to see that the function login_box sets the session and i want check_user to read it but it doesnt.

Try changing the line

$_SESSION['userinfo'] = '$user $pass';

to

$_SESSION['userinfo'] = "$user $pass"; //use double quotes instead of single

[sylesia]

A few things to try, first off, I am pretty sure if you do it the way you are, you need it to look like
$_SESSION['userinfo'] = $user . " " . $pass; // Took out quotes and added a period which binds them together with the space
Could have two variables if that does not work, a user and pass variable
Tell me what happens if you do the period one though, that should help you in what you need

The code
[code]<?php
$some_var = "$var1 $var2";
?>[/code]

and the code
[code]<?php
$some_var = $var1 . ' ' . $var2;
?>[/code]

produce the same result. Try it yourself.

The double quotes worked. Thanks for the help.
