PHP - Php Error Skipping Comment Lines

Hey, So what im trying to do is put my database variables into a session array. So this is what im trying to accomplish...

$_SESSION['Name_of_Row'] = $value

 This is the script I wrote:

Code: [Select]
Function setupSession(){
session_start();
$query = "SELECT * FROM users WHERE u_id ='{$this->u_id}'";
    $result = mysql_query($query);
        $row = mysql_fetch_array($result);

foreach($row as $key => $value){
    if(!empty($value)){
        $_SESSION[$key] = $value;   
            }
                }
}

When that runs I get the following warning. Can anyone tell me what this means and how to fix it?

Error: Notice: Unknown: Skipping numeric key 0 in Unknown on line 0

i get the following error in the comments in wordpress blog..:

Warning: preg_replace() [function.preg-replace]: No ending delimiter '~' found in /home/doughhhh/public_html/wp-content/themes/upload/includes/theme-comments.php on line 75

I am pretty new to PHP and am trying to create a simple (so I assumed) page to takes data from one html page(works fine) and updates a MYSQL Database.  I am getting no error message, but the connect string down to the end of the body section is showing up as plain text in my browser window.  I do not know how to correct this.  I have tried using two different types of connect strings and have verified my names from the HTML page are the same as listed within the php page.  Suggestions on what I need to look for to correct would be great.  I have looked online, but so far all I am getting is how to connect, or how to create a comment, so I thought I would try here. 
Thank you for any assistance I may get!!  - Amy -
