<?php // overly simplified example function test1() { $a = 3; test2(); } function test2() { echo $a; } // the actual idea is to do something like this // main.php $vars = []; function load_file($path) { if(is_file($path)) { $GLOBALS['path'] = $path; load_isolated(); } } function load_isolated() { extract($GLOBALS['vars']); require($GLOBALS['path']); $GLOBALS['vars'] = get_defined_vars(); } load_file('a.php'); // a.php $a = 3; load_file('b.php'); //b.php echo $a; // warning or error that var $a doesn't exist because get_defined_vars() was never called yata yata
