mysqli_multi_query store data into variable

[CarolHCX]

    //multi query
    $sql= "SELECT option_value FROM settings WHERE option_name = 'email_temp_issue';";  //1
    $sql .="SELECT title FROM books WHERE id = '$bookid';";  //2
    $sql .="SELECT fullName from students WHERE email = '$username'";  //3
    $sql_run = mysqli_multi_query($connection,$sql);
    if(mysqli_num_rows($sql_run)>0)
    {
        foreach ($sql_run as $row)
        {
            $email_template = $row['option_value']; //retrieve from query 1
            $title = $row['title']; //retrieve from query 2
            $name = $row['fullName']; //retrieve from query 3
        }
    }

I am trying to store the data from the multi query into each variable, which I am not sure how to do..Anyone can help? :)
