如何将 XML 元数据转换为适用于 SAML 2.0 的 PHP？答案

【问题标题】：How can I convert XML metadata to PHP for SAML 2.0?如何将 XML 元数据转换为适用于 SAML 2.0 的 PHP？
【发布时间】：2018-04-12 15:53:41
【问题描述】：

我尝试使用 SAML 2.0 与身份提供者作为服务提供者建立工作测试连接。我正在使用 Yii2 和 SimpleSamlPhp 库。为此，我需要在文件“simplesamlphp-sp/metadata/saml20-idp-remote.php”中填写身份提供者的元数据。问题是我只有 XML 文件。我知道可以使用http://saml.yourdomain.com/simplesaml/admin/metadata-converter.php 的内置工具将 XML 元数据转换为 PHP 但那个工具就是行不通。如果我粘贴我的 XML 文件并按“解析”页面将永远加载。

我已使用验证工具 (https://www.samltool.com/validate_xml.php) 检查了我的 XML 文件，它是有效的。

是否有任何在线工具可以将 XML 元数据转换为 PHP？

这里我使用 XML 以防万一：

@OlegAntoniuk 有一个用户邮件列表供人们提问：simplesamlphp.org/lists
