I'm starting to learn how to manage databases with
MySQL/PHP. The program is very basic but I have a
strange error: "Resource id #3".
I read many things on Internet and understood that
others have this error because they are trying to echo
the pointer of the query and not the result itself.
It's not my case so I don't understand.

Thank you very much for your help.

/*This program will log on to a users DB to check if
the user is allowed to log in or not.
The program checks the login and password of the user.
if (isset($_POST['login'])) {
if (isset($_POST['password'])) {

//log to the server
if ($db) {
//test if the connexion works
     if ($sel) {
        $sql_query="SELECT * FROM mytable WHERE
        if ($result) {
           //check if there is a result
           echo $result;
        //the query didn't work
        else echo mysql_error();
else echo mysql_error();
