将变量从受保护的函数传递到php中同一个类内的公共函数

Question

I have a class and two functions inside it as follows:

class MyClassName
{
    protected function myFunction1()
    {
        // some code here
        return $something;
    }
    public function myFunction2()
    {
        // some code here
        return $somethingElse;
    }
}

What I need to do is define a variable in myFunction1() and then use it in myFunction2(). What is the best practice to do that?

Answer 1

class MyClassName
{
    public $var = 0;
    protected function myFunction1()
    {
        // some code here
        $this->var = ...;
        return $something;
    }
    public function myFunction2()
    {
        // some code here
        echo $this->var;
        return $somethingElse;
    }
}
