Get filename of file which ran PHP include
include, php
Solution
An easy way is to assign a variable in the parent file (before the inclue), then reference that variable in the included file.
Parent File:
$myvar_not_replicated = __FILE__; // Make sure nothing else is going to overwrite
include 'other_file.php';
Included File:
if (isset($myvar_not_replicated)) echo "{$myvar_not_replicated} included me";
else echo "Unknown file included me";
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.
Problem
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?
