file1.php and file2.php with die(); function.
include.php:
<? include 'file1.php';
include 'file2.php' ?>
file1.php
<? echo 'included'; die(); ?>
file2.php
<? echo 'not included'; die(); ?>
How can I include both files with die(); function?
If I understand correctly what you are trying to do then unfortunately it isn't possible.
die();
will stop the script from executing at the point from where it is called.
