Unknown setter '_date_time' Carbon / Laravel 4

Question

I have my installation of laravel 4 under HHVM, and i set up as a accessory on my eloquent an converter date from SQL date to human.

doing something like that:

public function getDateSpanAttribute($value)
{
      return $value = \Carbon\Carbon::createFromFormat('Y-m-d H:i:s',$this->created_at)->diffForHumans();
}

This method work well under php5, no error just work. On HHVM this accessory throw me an exception saying,

{"error":{"type":"InvalidArgumentException","message":"Unknown setter '_date_time'","file":"/var/www/mynextmatch/vendor/nesbot/carbon/src/Carbon/Carbon.php","line":542}}

I saw the source of Carbon on that row and it is the magic method __get() to give this problem but i cannot figure out why it happening.

I will appreciate same help. Thanks

Not sure about the error on HHVM but one thing is for sure that an accessor method doesn't contain any argument, it should be (Manual):

public function getDateSpanAttribute()
{
      return \Carbon\Carbon::createFromFormat('Y-m-d H:i:s', $this->created_at)->diffForHumans();
}

You just need to return the property not setting anything, if you want to set anything then it would be a setter/mutator method which acepts a value as argument.

True, but it doesn't matter in fact.

Confused! Won't it matter if he doesn't provide the parameter while the method accepts one ? Method will complain about it, right ? But it doesn't matter if he provide it and doesn't use it in his code, like he is doing it now @deczo.

yes true, it doesn't matter with the problem but thank you, you are right! :)

You are welcome and please post the solution as an answer when you get it fixed, I'll delete my answer @Fabrizio.

I am having the same issue but think mine is tied to creating a session creation after logging in ( InvalidArgumentException Unknown setter '_date_time'). Mine is installed on HHVM 3.1 running on Ubuntu 14.04. I have the same set up using Ubuntu 12.04 and am not having this issue.

10. InvalidArgumentException
…/vendor/nesbot/carbon/src/Carbon/Carbon.php542
9. Carbon\Carbon __set
<#unknown>0
8. DateTime __sleep
<#unknown>0
7. serialize
…/vendor/laravel/framework/src/Illuminate/Session/Store.php222
6. Illuminate\Session\Store save
