Okay,
To everyone else who said they would like to learn PHP to help in developing mediawiki, - i put a message on the dev mailing list asking for any knowledgeble PHPer who would be willing to be our guide. If i get any replies (which hopefully i will) ill post a copy here. Also, there is a wikibook course on PHP, however i dont know what quality it is since i dont know PHP and cant judge (its an eternal loop isnt it?) also wikiversity might be worth checking out.
