php - 意义？ header ('P3P:CP=“IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT”');

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center。

我经常在下面的帖子中看到此代码。这是什么意思，这怎么会伤害或帮助某人将其添加到页眉？

ob_start();
header('P3P:CP="IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT"');

最佳答案

P3P是“隐私防护平台项目”。它旨在做出紧凑的隐私政策声明。

您可以根据this资源分解此语句:

IDC :这是一个访问描述符。这样可以访问可识别的联系信息。

DSP :这是有关争端解决的隐私策略 token 。

COR :您的服务错误将由您的服务纠正。

ADM :未经同意，可以将信息用于技术支持

DEVi :等，等等。(我不打算讲所有这些。)

我不知道为什么任何黑客都会将其放入 header 中，但是请确保您还原了更改。
