$result = $stmnt->fetchAll(); returning duplicate keys for a singlequery

[Rowan]

For some reason when I do a fetchall on a PDO query the array returned
has duplicated keys. see below.

SELECT name_first, name_last, personal_street, personal_phone_home,
personal_phone_cell FROM contacts WHERE id = 8;
$result = $stmnt->fetchAll();
<====krumo array dump===>
0 (Array, 12 elements)

id (Integer) 8

Helps when you read. For anyone curious the answer is below.

Controls how the next row will be returned to the caller. This value
must be one of the PDO::FETCH_* constants, defaulting to
PDO::FETCH_BOTH.

*

PDO::FETCH_ASSOC: returns an array indexed by column name as
returned in your result set
*

PDO::FETCH_BOTH (default): returns an array indexed by both
column name and 0-indexed column number as returned in your result set

To fetch assc is the best, so that your code depends less on the physical
structure of the table. both wastes space, and index not only has too much
dependency, but also makes code less readable. when $row['name_last'] has
clear meaning, $row[1] does not.
