PHP - Levels

I just added a user log on for a site I am building using PHP.  I used a simple session based system for this. I can log on just fine. What I am looking for is a way to pass on in ht session what rank a user is so some links/pages will only show for the admin or the super user but not the normal user. I rank the users as Admin 1, superuser 2, and user 3.

This is what I have for the session in my header that allows you to be logged in.
Code: [Select]
<?
session_start();
if(!session_is_registered(myusername)){
header("location:login.php");
}
?>

Here is what I have that starts the session
Code: [Select]

//Connection stuff

$query="SELECT * FROM user WHERE username='$myusername' and password='$mypassword'";
$result=mysql_query($query);

$count=mysql_num_rows($result);

if($count==1){

session_register("myusername");
session_register("mypassword");
header("location:index.php");
}
else {
echo "Wrong Username or Password";
}

ob_end_flush();
?>

Happy Monday All!

I am writing some code to try to pull in some XML from the TVA on lake levels.  This file is updated about every 3 to 4 hours.  I have the startings to pull the data in, but running into some problems.  Here is a break down of the problems.  I am fairly new to PHP, but trying to learn as I go.  Any help would be greatly appreciated.

The code I have will not pull in the data and display One I am able to display the code, I need to review the upsteam elevation and compare to the previous levels and show the lake rising, falling, or stable. Here is my code:

Code: [Select]
<?php
$html = file_get_contents('http://www.tva.gov/lakes/xml/OHH_R.xml');
$xml = simplexml_load_file('$html');
echo $html->getName() . "<br />";
foreach($xml->children() as $child)
  {
  echo $child->getName() . ": " . $child . "<br />";
  }
?>

 I am fairly new to PHP, but trying to learn as I go.  Any help would be greatly appreciated.

Hi everyone !
I am stuck on a task which I'm sure has been achieved by several others in the past.
I need to create a category table with unlimited / infinite levels (depths) of categories, sub-categories, sub-sub-categories, sub-sub-sub-categories and so on.
I need to know how to show the category tree through PHP.
An example would be great or even a link to another page where someone has laid out a step-by-step tutorial.

Please help!

Thank you very much!

Kind Regards,
Xeirus.
