爲什麼我的PHP如果週期不能正常工作

Question

我有這個PHP代碼，它做了測試並運行它，如果測試結果爲真。但即使它得到錯誤的結果，CastResult也會忽略if檢查。

private function canVote($user,$id) 
{ 
     $userVoted = VoteModel::where('user',$user)->where('post',$id)->get(); 
     if(count($userVoted)==0) 
      { 
       $canVote=true; 
      } 
     else { 
      $canVote=false; 
     } 
     return $canVote; 
    } 
    private function castVote($mode) 
    { 
     $user = Auth::getUser(); 
     $id = $this->param('id'); 

     if($this->canVote($user,$id)) 
     { 
      $newVote = new VoteModel; 
      $newVote->user = $user['name']; 
      //other stuff 

     } else 
      { 
       Flash::error('Err'); 
      } 
    }

更加簡單明瞭，沒有未定義的變量：

private function canVote($user,$id) 
{ 
    $userVoted = VoteModel::where('user',$user)->where('post',$id)->get(); 
    return (count($userVoted) === 0); 
}
