Use of
global functionality is not recommended; it makes your code harder to test, and less reusable.
Instead of relying on 1. Pass all data via parametersfunction myFunction($a, $b) {
// Do something
}
2. Create a class that maintains your stateclass MyClass {
private $a;
private $b;
public function __construct($a, $b) {
$this->a = $a;
$this->b = $b;

public function myFunction() {

2. Create a class that maintains your state
