Answer 1

cURL is most likely not installed correctly or linked up to PHP. Windows does not come with cURL installed (another reason to switch to a *nix based system! but I digress) so you'll need the appropriate dll files to enable it, then link those in via your php.ini file.

With regards to your current error, please check for syntax errors and leave a comment on this answer and update your provided source, and I'll modify.
