我是 apache PKI 证书和 php 的新手。我试图在 $_SERVER 数组 (php) 中找到 SSL_CLIENT_SAN_(email) 环境变量。我可以看到其他 mod_ssl 环境变量，但看不到 SSL_CLIENT_SAN_*。
我正在使用 wamp，如果这有任何影响
有我需要设置的配置吗？
我已经设置了：
SSLOptions +StdEnvVars
<FilesMatch "\.(cgi|shtml|phtml|php)$">
SSLOptions +StdEnvVars
</FilesMatch>
<Directory "/Apache24ah64/cgi-bin">
SSLOptions +StdEnvVars
</Directory>
我在 $_SERVER 中有以下内容：
