Fetch an element in an array

Hi,

This is more of a PHP problem, but I wish if someone knows this can help
me. How do I fetch an element in a Postgres array?

I have a table like

employee
--------
col1 int4
col2 text[]

now I used the php api

$row = pg_fetch_array($exec, 0);

which gives me the following:

echo $row['col2'];
(prints out ===> {"123-4567", "Bernie", "123-5670"} )

(echo $row['col2[2]']; <=== didn't work)

What can I do to extract only the "Bernie" element?

Thanks.
