Question

I have a problem. When I use global variables in my php code, my server doesn’t show any html code at all. If I comment out the global variable, my html page works just fine! Am I doing something wrong here?

php file:

class DBConnect{

    // If I comment this out, the HTML shows
    global $con;

    function connectDB() {
        $user = "bstokni_basurin";
        $pass = "basurin";
        $database = "basurin";
        $host = "localhost";

        $this->$con = mysql_connect($host, $user, $pass) or die(mysql_error());
        echo "Connected to MySQL </br>";
        echo $con;
    }

    function closeDB() {
        mysql_close($con);
        echo $con;
        echo "MySQL closed";
    }   
}

html file:

<!-- Left colon -->
            <div id="leftCol">
                <p>Her kemur ein menu at standa</p>
                <?
                    $menuObj = new DBConnect();
                    $menuObj->connectDB();
                ?>
            </div>

What am I doing wrong here?

Since the variable is in a class scope, try changing global to public instead. You don’t seem to need global in the example you have provided.
