Curl means client URL , php supports libcurl which allows
you to connect and communicate to many different types of
servers with many different types of protocals .libcurl
currently supports http,https,ftp,gopher,telnet and ldap
protocals.Once you have enabled the php with curl
support.you can use the curl functions.You can intialize a
curl session using the curl_init(),then you can set all
your options for the transfer via the curl_setopt(),then
you can execute the session wiht the curl_exec() and then
you can finish off your session using the curl_close().
