By default, mysqli_fetch_array() returns both an Associative Array ($key => $value) and a Numeric Array (0 => value), which is why you're getting duplicates - some of the entries have the column name as the key, the others have a numeric index.

If you want an associative array, you could use:

 mysqli_fetch_array($q, MYSQLI_ASSOC);
 //or
 mysqli_fetch_assoc($q);

Or for a numeric array:

 mysqli_fetch_array($q, MYSQLI_NUM);
 //or
 mysqli_fetch_row($q);
