Working on a small simple script not working right.

Ok I've made a class and put some functions in itand it's not returning what I want have a quick read first :
[code]
<?php

  require_once 'config.inc.php';

  class PHPApplication {

    function getName()
    {
$domain_user = explode("\\", $_SERVER['LOGON_USER']);
$user = $domain_user[1];

return $user;
echo $user;
}

function connect()
      {
        global $CONNECTION;

$CONNECTION = mssql_connect($INTRANET_DB_URL);
$this->connected == TRUE or die;
$this->connected == FALSE;
mssql_select_db($APP_DB);
$this->connected == TRUE or die;
$this->connected == FALSE;

echo $connected;
}

function authorise($user)
    {
global $CONNECTION;
echo $user;

if ($user == !null)
{
if (!mssql_query("SELECT USER_ID FROM users WHERE uNAME = {$user}", $CONNECTION))
{
echo "You are not entered in the Database, please see the Administrator";
exit;
} else {
$success == TRUE;
}
} else {
$success == FALSE;
}
return $success;

if ($success = TRUE)
{
$msg = "OK Your in";
} else {
$msg = "Get out";
}
echo $msg;
}

function run()
{
echo $this->getName();
echo "<BR/>";
echo $this->connect();
echo "<BR/>";
echo $this->authorise();
}
  }

$thisApp = new PHPApplication();

$thisApp->run();

?>
[/code]
Now all it echo's is my user name, so is $connected even instantiated and I don't know why $msg is being displayed.  Can someone point out where I'm going wrong and also if I could have just echoed $success to see TRUE/FALSE?  Thanks in advance

I'm watching this thread for a solution, but unable to provide one I'm afraid :(

in[code]$this->connected == TRUE or die;[/code]script die becouse the variable $connected is not set up

[scottybwoy]

Hmm OK that makes sense, I thaught that you could define a variable within the $this->  I looked it up in the php pages and couldn't find anything on it so could anyone explain how $this-> and $foo works and are they confined to classes or could you pass me into the right direction?

Also sasa i set up $connected and it still didn't do anything, thanks tho.

Right, now I've changed it around a bit and now it's not connecting to the database, here's the code :
[code]
<?php

  require_once 'config.inc.php';

  class PHPApplication {

    function getName()
    {
$domain_user = explode("\\", $_SERVER['LOGON_USER']);
$user = $domain_user[1];

return $user;
}

function authorise($user)
    {
global $CONNECTION;

mssql_select_db($APP_DB) or die("could not select database");

if ($user = !null)
{
if (!mssql_query("SELECT USER_ID FROM users WHERE uNAME = {$user}", $CONNECTION))
{
echo "You are not entered in the Database, please see the Administrator";
exit;
} else {
$success == TRUE;
}
} else {
$success == FALSE;
}
return $success;

if ($success = TRUE)
{
$msg = "OK Your in";
} else {
$msg = "Get out";
}
echo $msg;
}

function run()
{
global $CONNECTION;

$CONNECTION = mssql_connect($INTRANET_DB_URL) or die("Could not connect to Database");

echo $this->getName();
echo "<BR/>";
echo "<BR/>";
echo $this->authorise($user);


}

function userLevel()
{
global $CONNECTION;

$query = "SELECT TYPE FROM users WHERE USER_ID = $user_id";
$user_level = mssql_result($query, $CONNECTION);
}

  }

$thisApp = new PHPApplication();

$thisApp->run();

?>
[/code]

Is that because the connection is being droped by the time it calls the next function?

here's the error :

could not select databasePHP Warning: mssql_select_db() [function.mssql-select-db]: Unable to select database: in C:\Inetpub\wwwroot\database\classes\mri_central.php on line 28

Thank ppl

Right I have this code nearly working now, but it fails on this query :
[code]
<?php
function authorise($user)
{

mssql_select_db(APP_DB) or die("could not select database");

if ($user = !null)
{
if (mssql_query("SELECT USER_ID FROM users WHERE uNAME = $user") = TRUE)
{
echo "You are not entered in the Database, please see the Administrator";
exit;
} else if (mssql_query("SELECT USER_ID FROM users WHERE uNAME = $user") = FALSE) {
echo "Error upon Query, contact your administrator";
exit;
} else {
$success == TRUE;
}

} else {
$success == FALSE;
}

return $success;
}
?>
[/code]
Basically I have ommited my username for the database on purpose for it to fail on this query to bring up the message in the first clause.  But instead I get this error :

PHP Fatal error: Can't use function return value in write context in C:\Inetpub\wwwroot\database\classes\mri_central1.php on line 35

Can I not have = TRUE, or what is it saying.  Thanks
