this morning someone asked a very good questions. how can you find out whether or not you have CURL enabled on you linux php installation? well, finding out if you have CURL enabled in your php is easy. just create a phpinfo.php file and upload to your website and open it.

here is the code:
echo phpinfo();

then when you run phpinfo.php, look for the CURL section, if you have it enabled, it will say:
cURL support enabled
cURL Information libcurl/7.16.4 OpenSSL/0.9.8b zlib/1.2.3 libidn/0.6.8
