Which is the better approach to initialize php properties?

Question

Here are two way to initialize class variables.

1st Method

class Test {
    private $var1;
    private $var2;

    public function Test($var1,$var1) {
         


        

Answer 1

If those variables are necessary for the operation of the class, you would beter use the first method. That way you can ensure they are set when the class is created.
