http://curl.haxx.se/docs/caextract.html 下載證書 即可 然后在php.ini 改一下配置
windows8下運行php Composer出現ssl報錯的問題：
[Composer\Downloader\TransportException]
The "https://packagist.org/packages.json" file could not be downloaded: SSL
operation failed with code 1. OpenSSL Error messages:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify
failed
Failed to enable crypto
failed to open stream: operation failed
----類似以上錯誤
這是沒有安裝CA證書導致的！！！
CA證書下載地址：http://curl.haxx.se/docs/caextract.html
然后修改php.ini文件
openssl.cafile= D:/wamp/php/verify/cacert.pem
