This is my code:

```
<?php

function result($conn) {
      global $number;

    $sql = 'SELECT movie_name FROM movie_info LIMIT 3 OFFSET 0';
    foreach ($conn->query($sql) as $row) {
        print " ". $row['movie_name'] . " <br> ";

    }
}
result($conn);
?>

```

I am really confused, how to count the number of rows in the table and print it?
