I am getting this:
Array ( [0] => 1 [id] => 1 [1] => 778613c4344dbc9565c359c1154c6a18 [session] => 778613c4344dbc9565c359c1154c6a18 [2] => fn
Pascal MARTIN has already explained the reason behind it.
I'll tell you to use mysql_fetch_assoc It'll give you only the associated array. Numerical part will not be present.
mysql_fetch_assoc
