這個2個外掛就算是在php.ini裡面將extension=openssl，extension=curl前面的；去掉依舊不能新增成功。

官網上有一段話可以解決這個問題：

I had to also also copy libssh2.dll into my Apache24 folder for this 
to work with my PHP 5.6.2 installation. So altogether I had to do the 
following:

Move to Windows\system32 folder: 
libssh2.dll, php_curl.dll, ssleay32.dll, libeay32.dll

Move to Apache24\bin folder 
libssh2.dll 
Uncomment extension=php_curl.dll

將libssh2.dll, php_curl.dll, ssleay32.dll, libeay32.dll php_openssl.dll 移動到window\system32裡面就可以解決這個問題了。
