The property
beta does not exist. Did you maybe forget to declare it?
In PHP it is possible to write to properties without declaring them. For example, the following is perfectly valid PHP code: class MyClass { }
$x = new MyClass();
$x->foo = true;
Generally, it is a good practice to explictly declare properties to avoid accidental typos and provide IDE auto-completion: class MyClass {
public $foo;
}
$x = new MyClass();
$x->foo = true;

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() {
// Do something
}
}

The PSR-1: Basic Coding Standard recommends that a file should either introduce new symbols, that is classes, functions, constants or similar, or have side effects. Side effects are anything that executes logic, like for example printing output, changing ini settings or writing to a file.
The idea behind this recommendation is that merely auto-loading a class should not change the state of an application. It also promotes a cleaner style of programming and makes your code less prone to errors, because the logic is not spread out all over the place.
To learn more about the PSR-1, please see the PHP-FIG site on the PSR-1.
