Accessing a property inside a function defined in a method in PHP

Question

I need to call a function inside a method. This function needs access to a private property. This code:

class tc {
  private $data=123;

  public function test() {
    function test2() {
      echo $this->data;
    }

    test2();
  }
}

$a=new tc();
$a->test();

returns the following error:

Fatal error: Using $this when not in object context in ... on line ...

Using PHP 5.6.38. How can I do this?

Because test2 is a function within the test method, not a method in the tc object. You're not in the object scope. — Jonnix, Oct 25 '18 at 15:46
And the property is private, which means you can't access outside the object. — Felippe Duarte, Oct 25 '18 at 15:47
Why don't you make `test2` a real method instead of nesting it? — Barmar, Oct 25 '18 at 15:51
Note that functions nested inside a class method are NOT executed in class scope. So there's not much point in using nested functions like this. — Barmar, Oct 25 '18 at 15:56
My use case is to include different files that contain different test2 functions. — dj50, Oct 25 '18 at 16:33

Not sure why would you declare a function inside a method, but if that is what you want to do, then pass the private member as a parameter to this function.

<?php 

class tc {
  private $data=123;

  public function test() {
    function test2($data) {
        echo $data;
    }

    test2($this->data);
  }

}

$a=new tc();
$a->test();
