如何从 PHP 中的 SSL 证书文件中获取到期日期 [英] How to get Expiry date from the SSL Certificate file in PHP

问题描述

我想从 SSL 证书文件中获取到期日期.我创建了一个 PHP 网页，用户可以在其中上传他的 SSL 证书文件，我必须使用 PHP 获取该文件的到期日期.

解决方案

下面的代码应该会有所帮助:

 $url = "https://www.google.com";$orignal_parse = parse_url($url, PHP_URL_HOST);$get = stream_context_create(array("ssl" => array("capture_peer_cert" => TRUE)));$read = stream_socket_client("ssl://".$orignal_parse.":443", $errno, $errstr, 30, STREAM_CLIENT_CONNECT, $get);$cert = stream_context_get_params($read);$certinfo = openssl_x509_parse($cert['options']['ssl']['peer_certificate']);echo '
';打印_r($certinfo);echo '</pre>';
到期日期应在 $certinfo['validTo'] 字段下.
I want to get the expiry date from the SSL Certificate file. There is a web page in PHP that I've created, in which user can upload his SSL Certificate file and I will have to get the expiry date of that file using PHP.
解决方案
The code below should help:
    $url = "https://www.google.com";
    $orignal_parse = parse_url($url, PHP_URL_HOST);
    $get = stream_context_create(array("ssl" => array("capture_peer_cert" => TRUE)));
    $read = stream_socket_client("ssl://".$orignal_parse.":443", $errno, $errstr, 30, STREAM_CLIENT_CONNECT, $get);
    $cert = stream_context_get_params($read);
    $certinfo = openssl_x509_parse($cert['options']['ssl']['peer_certificate']);

    echo '<pre>';
    print_r($certinfo);
    echo '</pre>';
The expiry date should be under $certinfo['validTo'] field.
