A better habit and better way to organize codes is....
To put the actual functional codes into separate pages...
For example, you would actually split header, content(body) and footer into different pages and put the SQL connection page in a other file. Well, let's take a look...

For a Index page, you only have things that are necessary

<?php

$title ="Index Page";

include 'includes/header.php';
include 'includes/sqlconn.php';

$query = "SELECT * FROM bmark, category, user
            WHERE bmark.user_id = user.user_id
            AND bmark.category_id = category.category_id
            AND bmark.user_id='1'";

$test = sqlConnection($query);

while($row = mysql_fetch_array($test, MYSQL_ASSOC))
{
    printf("ID: %s Name: %s  Title: %s URL %s CAT %s", $row["user_id"], $row["user_name"], $row["page_title"], $row["url"], $row["category_name"]. "<br />");
}

sqlConnClose($test);

include 'includes/footer.php';
?>

So...what you see above are just basically includes and function calls. But in fact, you are implementing a whole page. Think about it.

okay, session control is not that hard at all.
IF you want to start a session, basically just call to session_start(), and it will do it.

to log on, you first need to connect to database and check to see if user and password match the database records.

a password/username check can be easily done with this:

function dataCheck($query)
{
    $result = sqlConnection($query);
    $check = mysql_num_rows($result);
    $checkResult = $check;

    sqlConnClose($result);

    return $checkResult;
}

and...the connection function is easy too

function sqlConnection($query)
{
    $sqlUsrName = "iw3htp4";
    $sqlPwd = "iw3htp4";
    $database = "bookmarks";

    mysql_connect('localhost',$sqlUsrName,$sqlPwd);
    @mysql_select_db($database) or die( "Unable to select database");

    $test = mysql_query($query);

    return $test;
}

so, you only need to check the return of the value is 0 or not. If it is 0, then it means it's mismatch.

To start a check, you simply select username and password and compare them.
Then, if match successful, you can start a session

[code lang = 'php']
include 'includes/sqlconn.php';
$query = "SELECT user_name, password FROM user
WHERE user_name='$usrName'
AND password='$usrPwd'";

$check = dataCheck($query);

//verify name and password
if($check === 0)
{
print ("

");
}

else
{
session_start();
$_SESSION['username'] = $usrName;

header( 'Location: index.php' ) ;
}
[/code]

well, not you have a session!
the following code is to check the existence of session and return a logout function

<?php

//check session existance and output links
function sessionCheck()
{
    session_start();
    if(isset ($_SESSION['username']))
    {

        $result = '<a href="manage.php" title="Click Here To Manage Your Personal Bookmarks and Account">Logged In as: ' . $_SESSION['username'] . '</a>
                    ' . '&amp;nbsp;' .'<a href = "?action=logout">[Logout]</a>';
        if(isset($_GET['action']))
        {
            $action = $_GET['action'];
            if ($action == "logout")
            {
                session_destroy();
                header( 'Location: index.php' ) ;
            }
        }
    }

    else
    {
        $result = '<a href="login.php" title="Click Here To Register Or Login">Login | Register </a>';
    }

    return $result;
}

//check session existance
function sessionExists()
{
    if(isset ($_SESSION['username']))
    {
        $result = true;

    }

    else
    {
        $result = false;
    }

    return $result;

}

• Unsorted list

– A list in which elements are placed in no particular order; 

the only relationship between data elements is the list 

predecessor and successor relationships 

• Sorted list Sorted list

– A list that is sorted by some property of its elements; there 

is an ordered relationship among the elements in the list, 

reflected by their relative positions

• Indexed list 

– A list in which each element has an index value associated 

with it

Well, I’m still up and writing Java. Now I seriously have no energy to write anything more. All the notes are in the comments, if you can’t understand it, check the block of comments or feed back to me. I can help you out if I have free time.
