Question

Ok I am learning php and trying out classes and functions. Currently I have multiple pages where it has the same menu bar and user info so I decided to create a class Common and a function menu to load user info and echo info and menu content. For some reason it is not displaying anything help?

class Content {
    public function menu($userid) {
        require_once("../class/class1.php");
        echo '<div id="logo"></div>
            <div style="clear:both;"></div>';
        echo '<div id="user">Welcome ';

        $db = new MySQL();
        $user = new User();
        $sql = $db->sql($user->loadUser($userid));

        if ($db->num_rows($sql) > 0) {
            while ($row = $db->fetch_array($sql)) {
                echo $row['name'] . ' ' . $row['lastname'];
            }
        }
    }
}

HTML:

require_once("content.php");
$content = new Content();
echo $content->menu($userid);

when running in localhost i get the following error:

Fatal error: Cannot redeclare class Sql in C:\xampp\htdocs\orbecargo\class\sql.php on line 3

that file is:

class MySQL
{
private $conexion;
private $total_consultas;

public function MySQL(){
    if(!isset($this->conexion)){
        $this->conexion = (mysql_connect("server","username","password")) or die(mysql_error());
        mysql_select_db("database",$this->conexion) or die(mysql_error());
        mysql_set_charset('utf8',$this->conexion);
    }
}
}

the weird thing is that other pages work perfectly…
and I removed the

echo $content->menu($userid);  

and still nothing

Answer 1

echo $content->menu($userid);

menu() does not return anything

remove the echo before the menu(); to

require_once("content.php");
$content = new Content();
$content->menu($userid);
