Question

for($i=0;$cast_row = mysql_fetch_array($res);$i++)
{
    $cast['id'][] = $cast_row['user_id'];
    $cast['role'][] = $cast_row['role'];
    $cast['role_name'][] = $cast_row['role_name'];
    $cast['is_approved'][] = $cast_row['is_approved'];
    $cast['movie_id'][] = $cast_row['movie_id'];
}
for($i=0;$i<count($cast['id']);$i++) //LINE 31
{
    $output .= "<tr>";
    $mname = getMovieNameById($m_id);
    $output .= "<td><a href='single.php?id=$m_id'>$mname</a></td>";

    $aname = getArtistNameById($cast['id'][$i]);
    $output .= "<td><a href=project.php?id={$cast['id'][$i]}>$aname</a></td>";
}

This code works fine in the web server but throws errors(notice) when executed on localhost

Notice: Undefined index: id in C:\wamp\www\Tinyflick\managemovie.php on line 31

What can be the problem? The rest of the code seems to work just fine

Answer 1

It kind of a silly mistake..
Its solved. Thanks to nico’s comment

The error reporting level in localhost is different from the one on the server.
Changing that will do the trick.
The following code will show the all the errors and warnings

error_reporting(E_ALL)

Warnings are usually disabled on a production server. For more info refer the documentation of the said function
