Question

I have a simple PHP class, I’m trying to access a property of that class from a method in that class. I’ve tried the $this->property_name syntax and that doesn’t appear to work. What am I doing wrong?

class NavigationBuilder {

    public $mPage;
    public $mGeoID;
    public $mContinent;
    public $mCountry;
    public $mRegion;

    private $Geograph = 'a';

    public function construct_navigation() {

    }

    public function __construct() {

        var_dump($Geograph);
    }

}

Answer 1

You are correct that you need to use $this->property.
Your example works if you use $this

<?php

class NavigationBuilder {

    public $mPage;
    public $mGeoID;
    public $mContinent;
    public $mCountry;
    public $mRegion;

    private $Geograph = 'a';

    public function construct_navigation() {

    }

    public function __construct() {

        var_dump($this->Geograph);
    }
}

// prints string(1) "a"
$geo = new NavigationBuilder();
