The local development environment uses WAMP to build quickly, and there may be an inability to load when using PHP's curl, providing the ultimate solution.
1. Enable the Php_curll.dll extension in the php.ini configuration file (the environment is automatically shipped with Libeay32.dll,ssleay32.dll).
2, a variety of network on the Libeay32.dll, Ssleay32.dll, Php_curll.dll copy to the System32 method is very inappropriate, the normal method should be this: My Computer, right-click Properties, advanced system settings, environment variable, system variable, find path system environment variable, edit path variable value add PHP environment root, save.
3. Restart the server and see if the path variable joins successfully on the cmd command line.
Above 3 steps, easy to solve the development when curl can not load the problem, the end.
The ultimate solution to the invalid Windows Curl extension.
