Question

I have a function called

chewbacca() {
    include('external.php');
    echo $lang[1];
    ...
    }

The file external.php contains all the $lang array. However, since I have to execute the function thousands of times, I would like to include only once the file. If I include_once(‘external.php’); before the function, how can I use the $lang array variables in my function without having to write “global” before each use?

Answer 1

Unless I’m misunderstanding what you’re after, you don’t need to write global before each use, you just have to use it at the start of the function.

include('external.php');

chewbacca() {
    global $lang;
    echo $lang[1];
    ...
}
