Your xampp installation most likely already has curl support built-in. You just have to turn it on. It’s not difficult at all. That’s not necessary for Windows versions of PHP.
Find your php.ini file (probably in xampp\apache\bin\php.ini and open it in notepad or another plain text editor
search for the line that says:
remove the semicolon from the beginning of the line.
save the file
check a phpinfo() program to see if you now have curl support listed.
In a standard xampp build, this is all you have to do. If you installed apache and PHP in another way, you might need to move some dlls to the windows\system directory.
(libeay32.dll and ssleay32.dll)
Best of luck to you.
