mysql_fetch_array with MYSQL_BOTH or MYSQL_ASSOC is returning one of the columns in the query ONLY as a numeric index, but not the named index.  The column is a NOT NULL column, so the value is always defined.

I have a feeling the problem has something to do with the fact that the "missing" column is the column joining two tables.  Here's the SQL:

select distinct p.*,pt.Formula 
from Promotions p, PromoTypes pt 
where p.PromoTypeID = pt.PromoTypeID 


Here's some of the result of mysql_fetch_array:

array(31) {
  [0]=>
  string(2) "10"
  ["PromotionID"]=>
  string(2) "10"
  [1]=>
  string(20) "Free font with order"
  ["Name"]=>
  string(20) "Free font with order"
  
  ...etc...

  [7]=>
  string(2) "10"
  [8]=>
  string(4) "0.01"
  ["X"]=>
  string(4) "0.01"

  ...etc...
}


Array index 7 should be followed by the key "PromoTypeID".  The same thing happens using MYSQL_ASSOC (the element is missing altogther), and also if I specify p.PromoTypeID explicitly in the query.

The problem IS SOLVED if I alias the column name to something else using "p.PromoTypeID AS FakeName" , which makes me think even more that it's being confused by the table joining.
