php_curl extension support under ubuntu linux
1. Create a new test.php file in the web server directory (usually /var/www under Ubuntu)
　2. Edit the file and type the following line of code: phpinfo();
　3. Save the file
　4. Open the browser, Browse this page. (For example: http://localhost/test.php) 5. Search for "curl" to see if curl has been installed. If you don't find it, it must have not been installed. Please see below to install it.
　The installation method is very simple and only requires one command. (I choose direct apt-get installation here, because it is much simpler than compiling by yourself, and you don’t need to configure anything yourself)
　# sudo apt-get install curl libcurl3 libcurl3-dev php5-curl
　Congratulations, PHP5 cURL is installed. Remember to restart the Apache server
　 # sudo /etc/init.d/apache2 restart
　 If you still have problems, try editing your php.ini file (mine is /etc/php5/apache2/php.ini) and add at the end One line: extension=curl.so Save the file and restart the Apache server.
