It helps to RTFM. In any case the name of the function mysql_fetch_array() kind of gives the game away :) > You'll see below that I hacked a work-around by > using a "foreach()" statement, which works flawlessly. That is common practice when dealing with arrays. > How can I grab a specific field of an array without using a foreach()? > while ($line = mysql_fetch_array($result, MYSQL_ASSOC)) If you know the names of the fields, then you can access them directly by: $value_of_field = $line['name_of_field']; If you had used: while ($line = mysql_fetch_array($result, MYSQL_NUM)) Then you would have to reference the fields using: $value_of_field_0 = $line[0]; Remember the manual is your friend.
