They should contain the same information. However, historically and technically speaking, there is a difference between the two.
它们应该包含相同的信息。但是，从历史和技术上讲，两者之间存在差异。
SCRIPT_NAMEis defined in the CGI 1.1 specification, and therefore is a standard. This means it should be available no matter what scripting language you're using.
SCRIPT_NAME在 CGI 1.1 规范中定义，因此是一个标准。这意味着无论您使用哪种脚本语言，它都应该可用。
PHP_SELFis implemented directly by PHP, and as long as you're programming in PHP, it will be there.
PHP_SELF是直接用PHP实现的，只要你用PHP编程，它就在那里。

Most of the time it's the same, but $_SERVER['SCRIPT_NAME']is less spoofable than $_SERVER['PHP_SELF'], so you should use SCRIPT_NAMEif you want to reuse that data somewhere on your output.
大多数情况下它是相同的，但$_SERVER['SCRIPT_NAME']比 更不易被欺骗$_SERVER['PHP_SELF']，因此如果您想在输出的某处重用该数据，则应使用SCRIPT_NAME。
