php警告与严格标准

Question

I am using $_SESSION['']; to get values from a user after they have logged in. This data is coming from the users table.

I am then trying to

`SELECT *` `FROM roster`

by doing a query and assigning a var for each value when the users API=$API

I can do so by using the following:

error_reporting(E_ALL);

    include ('database_connection.php');
    $API        = $_SESSION['API'];

        if ($API !== false) { 
            $roster_query = "SELECT * FROM roster WHERE API='$API'";
            $result = mysqli_fetch_array(mysqli_query($dbc, $roster_query));

    /* ROSTERS TABLE */
            $StreetName     = $result['streetname'];
            $HouseNum   = $result['housenumber'];
            $City       = $result['city'];
            $State      = $result['state'];     
            $Zipcode        = $result['zipcode'];                               

    /* SESSION */
            $FirstName  = $_SESSION['firstname'];
            $LastName   = $_SESSION['lastname'];
            $Email      = $_SESSION['email'];

    /* this->$vars - Specific for this form */      
            $ExecutionDate  = date("Y:M:D");      
            $DOCSIGNEDBYIP  = $_SERVER['REMOTE_ADDR'];

        }

However, I get the following errors when I do. If I remove the above code no errors, etc.

Now this isnt 'breaking' my code, but I do not want to sweep this under the rug and resolve later.

Can someone identify where I am going wrong ?

Answer 1

Try these, see if they work:

// Set an empty object for $return first
$return =   new stdClass();

if( ! $return_array ) {
    $i = 0;
    while ( $row = mysql_fetch_object($sql_query) ) {
        $return->$i = $row;
        $i++;
    }

I think the other is saying you should have is_logged() as a static function:

class Access
    {
        static function is_logged()
            {
                // code here
            }
    }

Answer 2

1. check $row use !empty($row) ( just Warning )
2. can not find static functon is_logged()
