Instead of relying on `global` state, we recommend one of these alternatives: 1. Pass all data via parameters function myFunction($a, $b) { // Do something } 2. Create a class that maintains your state class MyClass { private $a; private $b; public function __construct($a, $b) { $this->a = $a; $this->b = $b; } public function myFunction() { // Do something } } Loading history...
