constructor repository access .. getting error

i getting error :

errorexception in familyservice.php line 19: object of class app\repositories\eloquent\familyrepository not converted string in familyservice.php line 19 @ handleexceptions->handleerror('4096', 'object of class app\repositories\eloquent\familyrepository not converted string', 'd:\files\xampp\htdocs\laravel\dolovers-project-nayeb-moshai\app\services\familyservice.php', '19', array('familyrepository' => object(familyrepository))) in familyservice.php line 19 @ familyservice->__construct(object(familyrepository)) @ reflectionclass->newinstanceargs(array(object(familyrepository))) in container.php line 817 @ container->build('app\services\familyservice', array()) in container.php line 656 

when access class variables, need $this->some_var, not $this->$some_var. in latter case, php thinks you're trying use string value of $some_var, , can't - that's why it's complaining not being able convert string.

just changing should work right away, assuming other code correct.

public function __construct(ifamilyrepository $familyrepository){     $this->familyrepository = $familyrepository; }  public function testrepository(){     $this->familyrepository->getallgrandfather();     return "null"; } 

(also, beside - , know better me - should ifamilyrepository, not familyrepository?)
