PHP Error Help....Notice: Unknown: Skipping numeric key 0 in Unknown on line 0

[vicodin]

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:

 

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
