[wp-hackers] array_push on update_user_meta

[J.D. Grimes]

Yes, when you call get_user_meta() you need to set the third parameter ($single) to true:

$active_user_friends = get_user_meta( $active_user, ‘friends’, true );

Otherwise it will return a nested array. Also, just FYI, alternatively you could leave the get_user_meta() call the way it is, and change it so that each friend is stored in a separate meta row (but with the same meta key - have a look at the *_user_meta functions on the codex).
