Subject: Re: [PHP-DEV] array_seek function
From: pierre.php@gmail.com (Pierre Joye)

hi Felix,

Not sure about the usefulness of this function but the name is
misleading (pls reattach the patch as .txt while being at it :). Does
it set the position (_seek) or does it return the value of a given
position (_get_pos)? or both (no idea :)?

Cheers,

Cheers,
