The Curl module is not opened in PHP. If we need to open it, we need to simply configure it. Now I will introduce the method of installing and configuring PHP Curl in the WAMP environment. Students can refer to it.
1. Copy the two files libeay32.dll and ssleay32.dll in the PHP directory to the WINDOWS/SYSTEM32 directory;
2. Modify extension=php_curl.dll in the PHP.INI file and remove the previous comment (that is, remove the colon);
3. Restart the wamp service.
