php - 使用 curl_error 发出请求时出错

Question

我从 PHP 5.3 升级到 5.4 (easyphp)，现在出现以下错误：

Exception: TestCaseCtrlSignUp -> testSignUp -> Unexpected PHP error [Error making request with curl_error: error:14077102:SSL routines:SSL23_GET_SERVER_HELLO:unsupported protocol] severity [256] in [C:\Program Files (x86)\EasyPHP-12.0\www\workspace\CPS\lib\campain_monitor\class\transport.php line 132]
