Access values in PHP object - php

Question

I have the following PHP object, which I want to access specific values from it but I have difficulties in understanding how to start:
kamranahmedse\Geocode Object (
[service_url:kamranahmedse\Geocode:private] => http://maps.googleapis.com/maps/api/geocode/json?sensor=false
[service_results:kamranahmedse\Geocode:private] => stdClass Object (
[results] => Array (
[0] => stdClass Object (
[address_components] => Array (
[0] => stdClass Object (
[long_name] => 112
[short_name] => 112
[types] => Array (
[0] => street_number
)
)
[1] => stdClass Object (
[long_name] => Imittou
[short_name] => Imittou
[types] => Array (
[0] => route
)
)
[2] => stdClass Object (
[long_name] => Cholargos
[short_name] => Cholargos
[types] => Array (
[0] => locality
[1] => political
)
)
[3] => stdClass Object (
[long_name] => Cholargos
[short_name] => Cholargos
[types] => Array (
[0] => administrative_area_level_5
[1] => political
)
) ...
For example how can I access:
[long_name] => Cholargos

Answer 1

The variable you're trying to access is private and therefore you're not going to be able to access it directly.
A better way is to use the methods provided by the class you're using.
Looking at the code you've provided I can see that you're using https://github.com/kamranahmedse/php-geocode
Here's an example of how it can be used to get the locality:
<?php
require __DIR__."/vendor/autoload.php";
use kamranahmedse\Geocode;
$address = "Imittou 112 Cholargos 155 61 Greece";
$geocode = new Geocode($address);
echo $geocode->getLocality();
Also, looking at the class source code we can see that when the address information is retrieved and local variables populated the long_name is used to populate the locality, which is what you want:
$this->locality = $component->long_name;
So the above code example should answer your question.
