[TYPO3-english] PHP: Get page title of linked page

[Sergey Alexandrov]

Well, take a look on the rsgoogleanalytics. He uses a TYPO3 hook into 
TYPOLink Generation called linkPostProcess(&$params, &$reference)
This hook called every time while processing any link, so it's very easy 
to modify any link on your page(s) "on the fly"

Hope it could help you,

Serg
