PHP 通过域名检测验证SSL证书 因为测试域名比较多，而且强迫症就全加了免费的ssl，时间长了经常忘记，导致有的时候访问出错，所以就想着做个检测验证，刚好在网上也找到了，就记录一下工作流程添加域名列表添加定时器，访问检测链接检测链接，邮箱通知错误域名检测ssl方法function get_cert_info($domain){ $context = stream_context_create(['ssl' => [ 'capture_peer_cert' => true, 'capture_peer_cert_chain' => true, ], ]); $client = stream_socket_client("ssl://".$domain.":443", $errno, $errstr, 30, STREAM_CLIENT_CONNECT, $context); if($client==false) { return false; } $params = stream_context_get_params($client); $cert = $params['options']['ssl']['peer_certificate']; $cert_info = openssl_x509_parse($cert); return $cert_info; }调用方法$domain = 'www.baidu.com'; $cert_info = get_cert_info($domain); $validTo_time_t = $cert_info['validTo_time_t']; $validTo_time_d = date('Y-m-d H:i:s', $validTo_time_t); echo($validTo_time_d);
