Do not use any of the suggested versions of PHP_SELF. It is a security nightmare, opening up your PHP to a multitude of possible injection attacks.
不要使用任何建议的 PHP_SELF 版本。这是一个安全噩梦，让您的 PHP 面临多种可能的注入攻击。
What are you trying to achieve? Generate the URL for a form sending to itself? Use action=""for that - it is a valid approach and will always use the URL for sending the form as for loading.
你想达到什么目的？为发送给自身的表单生成 URL？action=""为此使用- 这是一种有效的方法，并且将始终使用 URL 来发送表单作为加载。
If you must know the requested script, use $_SERVER['SCRIPT_NAME']instead.
如果您必须知道请求的脚本，请$_SERVER['SCRIPT_NAME']改用。

Looks like certain WordPress distributions declare $PHP_SELF = $_SERVER['PHP_SELF']for reasons I can't say, must be some sorta legacy thing.
看起来某些 WordPress 发行版声明$PHP_SELF = $_SERVER['PHP_SELF']的原因我不能说，一定是某种遗留的东西。

Some shells will erase the value of $_SERVER['PHP_SELF']as a security measure. You may need to look at $_SERVER['argv'][0]if this is what is happening to you.
$_SERVER['PHP_SELF']作为一种安全措施，一些 shell 会擦除 的值。您可能需要看看$_SERVER['argv'][0]这是否是发生在您身上的事情。
