How do I get every array/variable from another php file without knowing variables/arrays names

I have a file named “example.php”:

<?php

I want to get every variable/array from “main.php” without knowing every variable/array name. Is it possible?

get_defined_vars gives me every variable from the whole system so it’s not what I need.

Answer

Despite the comments correctly suggesting to think about whether this is a preferrable approach at all (see XY problem), I still think this might be a niche use-case that warrants a solution (after all, we simply don’t know all the legitimate use-cases that may exist).

So here’s what you can do: Use get_defined_vars() after and before requiring the file. Then just include all the variables that didn’t exist before the require (array_diff will not work in this case, as it will throw an “array to string conversion” error).

<?php
$vars_before = get_defined_vars();

require 'example.php';

$vars_after = array_filter( get_defined_vars(), function( $key ) use ( $vars_before ) {
    return ! array_key_exists( $key, $vars_before ) && $key !== 'vars_before';
}, ARRAY_FILTER_USE_KEY );

var_dump( $vars_after );
