Attention matters

Curl () is very efficient, support multithreading, but need to open the curl extension. The following are the steps to open the Curl extension:

1, the PHP folder under the three files Php_curl.dll,libeay32.dll,ssleay32.dll copy to the System32;

2, in the php.ini (c:windows directory) in the Extension=php_curl.dll in the semicolon removed;
3, restart Apache or IIS.
