How can I overwrite a protected property of an object?

Question

This is the result of dd($followers):

LengthAwarePaginator {#401 ▼
  #total: 144
  #lastPage: 8
  #items: Collection {#402 ▼
    #items: array:18 [▶]
  }
  #perPage: 20
  #currentPage: 1
  #path: "http://myurl.com/SocialCenter/public/twitterprofile/JZarif"
  #query: []
  #fragment: null
  #pageName: "page"
}

Now I want to know, how can I overwrite #total? I mean I want to reinitialize it to 18. So this is the expected result:

LengthAwarePaginator {#401 ▼
  #total: 18
  #lastPage: 8
  #items: Collection {#402 ▼
    #items: array:18 [▶]
  }
  #perPage: 20
  #currentPage: 1
  #path: "http://myurl.com/SocialCenter/public/twitterprofile/JZarif"
  #query: []
  #fragment: null
  #pageName: "page"
}

Is doing that possible?

Noted that none of these work:

$followers->total = 18;
$followers['total'] = 18;

Why would it change from 144 to 18? What are you really trying to do? — Ohgodwhy, Jul 31 '17 at 05:27

You could use reflection:

$reflection = new \ReflectionObject($followers);

$property = $reflection->getProperty('total');

$property->setAccessible(true);
$property->setValue(
    $followers,
    18
);

For reference, see:

What's `9001` ? – Martin AJ Jul 31 '17 at 05:24

Just an arbitrary new value for the `totals` property. – localheinz Jul 31 '17 at 05:25

You should make a getter and setter function.

But you can use PHP-Reflections. Like this example:

<?php
class LengthAwarePaginator
{
    private $total = true;
}

$class = new ReflectionClass("LengthAwarePaginator");
$total = $class->getProperty('total');
$total->setAccessible(true);
$total->setValue(18);

The property isn't accessible, you need to use http://php.net/manual/en/reflectionproperty.setaccessible.php first. – localheinz Jul 31 '17 at 05:28
