php curl ssl https 錯誤的 排除

curl 抓 https 時會出現以下的錯誤

Failed: Error Number: 60. Reason: SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

原因是 ssl 無法驗証成功
解決方法一：

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);

解決方法二：
先用火狐或ie開啟連結，下載其 crt 檔，放到自已站中

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_CAINFO, getcwd() . "/path/download.crt");

缺點要自行注意到期日，重下新的 crt檔
