Use of global functionality is not recommended; it makes your code harder to test, and less reusable.
                                                                                                

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
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
    }
}
