获取运行PHP包含的文件的文件名 [英] Get filename of file which ran PHP include

问题描述

使用PHP include 时，如何找出调用 include 的文件？简而言之，父文件的文件名是什么？

When using the PHP include, how can I find out which file is calling the include? In short, what is the parent's file filename?

推荐答案

一种简单的方法是在父文件中分配一个变量（在包含），然后在包含的文件中引用该变量。

An easy way is to assign a variable in the parent file (before the inclue), then reference that variable in the included file.

父文件：

$myvar_not_replicated = __FILE__; // Make sure nothing else is going to overwrite
include 'other_file.php';

包含文件：

if (isset($myvar_not_replicated)) echo "{$myvar_not_replicated} included me";
else echo "Unknown file included me";

您还可以使用 get_included_files（） 或 debug_backtrace（） 并查找包含文件的时间和地点，但这可能会有点麻烦和复杂。

You could also mess around with get_included_files() or debug_backtrace() and find the event when and where the file got included, but that can get a little messy and complicated.
