function flickr_user_find_by_identifier in Flickr 6

Same name and namespace in other branches

1. 5 flickr.inc \flickr_user_find_by_identifier()
2. 7 flickr.inc \flickr_user_find_by_identifier()

Tries to match an 'identifier' onto a flickr nsid.

This function will first see whether $identifier is already a nsid (format check only, no api call). If it is not and the identifier has the format of an email, an api call will be made to check whether there is an nsid for that email. If this is not the case, the $identifier is treated as a username and an api call is made to find the nsid for that username.

If none of these succeed, the result will be false

Parameters

$identifier: identifier to find an nsid for

Return value

valid nsid or false if none can be found
