video embedding php file error

hi everyone,
i am running jomsocial( a joomla social networking component)on mysql database.there you have an option to link videos from different video sharing sites(like youtube, metacafe). they only cover some popular sites. i have come to know that if you add a php file to the video library of this component similar to the ones already in there you can link video to a new site.for example if i add two php files for tudou.com and youku.com (these are the most popular video sharing sites in china) i will be able to link video with this sites.they already have php files for youtube,yahoo,metacafe etc.if i add two php files to that library naming the two sites it should work.but i am getting some errors i dont understand. i am new to programming world.can anyone please help me to edit this files properly.please download the files from the attachment.thank you
