$priv_key = file_get_contents("pcarduser-sandbox-fzh.pem");
$pkeyid = openssl_get_privatekey($priv_key);//运行到这里就报错
fatal error: call to undefined function openssl_get_privatekey()
openssl_sign($kq_all_para, $signmsg, $pkeyid,openssl_algo_sha1);// compute signature
openssl_free_key($pkeyid);
// free the key from memory
$kq_sign_msg = base64_encode($signmsg);
求大神 ！ 帮帮忙啊！
回复讨论(解决方案)openssl_pkey_get_private().具php.net上是说这个方法是一个别名,尝试下这个方法.
