Share variables between classes in PHP

I have several classes as in the example.

class clase1 extends padreclase1 {
 var $variable1 = 'valor1';
  var $variable2    = 'valor2';
}

class clase2 extends padreclase2 {
var $variable1  = 'valor1';
var $variable2  = 'valor2';
}

The value of the variables will be the same in all cases, but I would not like to have to repeat their writing in all classes.

How can I do to put those variables in a file or similar and then be inserted at the beginning of each class? Since they must be attributes of each class.

For this case, if you have different classes in origin and all yours have to:

1.- inherit from some defined classes of your framework, different from each other.

2.- contain attributes in each of them, equal

The solution is to use traits: link

For example, in your case, you could do:

trait VariablesGeneralesTrait {
    var $variable1 = 'valor1';
    var $variable2 = 'valor2';
}


use VariablesGeralesTrait;
class clase1 extends padreclase1 {
 trait VariablesGenerales;
}


use VariablesGeneralesTrait;
class clase2 extends padreclase2 {
 trait VariablesGenerales;
}

With this, a "lateral inheritance" occurs, so that all the classes that "use" the trait, have the same attributes (and even methods).
