When using the link as shown above (with localized name spaces!!!), there is no information about the page ID delivered in the serialized PHP output, only a index key in the array which sizeof() can't detect. This renders the backlink function pretty unusable as I can't access the page's backlinks. Strange is, if you use English namespace names like in http://de.wikipedia.org/w/query.php?what=backlinks&titles=User:HardDisk&bllimit=11&format=php the page ID is delivered at $array["pages"][-1]["refid"].
The array key missing is at http://mediawiki.pastey.net/6501?hi=250 (line 250)
Referring to http://mediawiki.pastey.net/6500, which is the result of print_r( unserialize( <contents of URL in URL field> ) ), it's quite obvious that there is an easily accessible page identifier, and this is duplicated, in fact, so it's quite possible to access the information required. I'm guessing that the information Marco's talking about is injected to indicate any applicable namespace translations between languages and so forth, and so won't be present when viewing the thing in German. We should *probably* be consistent about providing this.
Well, you cannot access the page ID that easily. It is hidden in itself (lines 160/164 at http://mediawiki.pastey.net/6501), so you cannot access them without a really huge mess with foreach.
Same thing is going on with imageinfo. Again, here the image ID is hidden in itself when the name supplied is English namespace.
So if I understand you well, you are complaining about the fact that Array ( [12345] => Array( [pageid] => 12345 etc. ) ) (rough sketch) hides the pageid inside the pageid. This is true. But you may be forgetting that backlinks can take multiple page titles: http://de.wikipedia.org/w/query.php?what=backlinks&titles=User:HardDisk|User%20talk:HardDisk&bllimit=11 in which case the result looks like: Array ( [12345] => Array( [pageid] => 12345 [title] => User:HardDisk more info ) [130569] => Array( [pageid] => 130569 [title] => User talk:HardDisk ) ) So you will *have* to foreach() the pages array, which contains only one element if you specified one title (or two if the title had to be localized). Foreach()ing on a one-element array doesn't sound that horrible to me, especially considering what=backlinks is designed to be usable for multiple targets in one request.
Closing as INVALID. If you still have complaints, please reopen this bug.
