Are there any alternative approaches to setting default values for method parameters in PHP classes?

In PHP classes, default parameter values for methods can be set using the traditional method of assigning default values in the method signature. However, an alternative approach is to use the null coalescing operator (??) inside the method to check if a parameter is null and assign a default value if it is. This can be useful when you want to set default values based on certain conditions or dynamic values. 

class Example {
    public function exampleMethod($param1 = null, $param2 = null) {
        $param1 = $param1 ?? 'default_value1';
        $param2 = $param2 ?? 'default_value2';
        
        // Rest of the method code
    }
}
