The description of the "$section" parameter to imap_fetchbody is woefully inadequate. At the very least, it could use links to the 
relevant parts of the IMAP standard it refers to, which (as far as I can determine) are § 6.4.5 "FETCH Command"  
(http://tools.ietf.org/html/rfc3501#section-6.4.5) and the definition of fetch-att in § 9 "Formal Syntax" 
(http://tools.ietf.org/html/rfc3501#section-9) on page 85 (http://tools.ietf.org/html/rfc3501#page-85).

A note such as the following would be helpful (though it should be checked for accuracy):

"Since PHP array indices are 0-based while section numbers are 1-based, you must add 1 to the index of any section taken from the result 
of imap_fetchstructure before using it with imap_fetchbody. For example, if $parts is the result of imap_fetchstructure, $parts[0] would 
correspond to section number "1", and $parts[2][1][0] corresponds to "3.2.1"."
