$projects = DB::table('projects')->where([['title','like','%'.$input.'%'],
    ['status','<>','Pending'],
    ['status','<>','Not Available']])
->orwhere([['owner', 'like', '%'.$input.'%'],
    ['status','<>','Pending'],
    ['status','<>','Not Available']])->get();

在这种情况下，你可以使用这样的代码:

User::where('this', '=', 1)
    ->whereNotNull('created_at')
    ->whereNotNull('updated_at')
    ->where(function($query){
        return $query
        ->whereNull('alias')
        ->orWhere('alias', '=', 'admin');
    });

它应该为你提供这样的查询:

SELECT * FROM `user` 
WHERE `user`.`this` = 1 
    AND `user`.`created_at` IS NOT NULL 
    AND `user`.`updated_at` IS NOT NULL 
    AND (`alias` IS NULL OR `alias` = 'admin')

如果你的条件是这样的(匹配一个值)，一个简单的更优雅的方式是:

$results = User::where([
         'this' => value,
         'that' => value,
         'this_too' => value,
          ...
      ])
    ->get();

但如果你需要OR子句，那么确保你对每个OR where()子句重复必须满足条件。

    $player = Player::where([
            'name' => $name,
            'team_id' => $team_id
        ])
        ->orWhere([
            ['nickname', $nickname],
            ['team_id', $team_id]
        ])

你可以这样做，这是最短的方法。

    $results = User::where(['this'=>1, 
              'that'=>1, 
               'this_too'=>1, 
               'that_too'=>1, 
              'this_as_well'=>1, 
               'that_as_well'=>1, 
                'this_one_too'=>1, 
               'that_one_too'=>1, 
              'this_one_as_well'=>1,
                'that_one_as_well'=>1])->get();

在Laravel 5.3中(在7.x中仍然如此)，你可以使用更细粒度的数组:

$query->where([
    ['column_1', '=', 'value_1'],
    ['column_2', '<>', 'value_2'],
    [COLUMN, OPERATOR, VALUE],
    ...
])

就我个人而言，我还没有发现这个用例超过多个where调用，但事实是你可以使用它。

自2014年6月起，您可以将数组传递到where

只要你想要所有的where use和operator，你可以这样分组:

$matchThese = ['field' => 'value', 'another_field' => 'another_value', ...];

// if you need another group of wheres as an alternative:
$orThose = ['yet_another_field' => 'yet_another_value', ...];

然后:

$results = User::where($matchThese)->get();

// with another group
$results = User::where($matchThese)
    ->orWhere($orThose)
    ->get();

以上将导致这样的查询:

SELECT * FROM users
  WHERE (field = value AND another_field = another_value AND ...)
  OR (yet_another_field = yet_another_value AND ...)

多个where子句

    $query=DB::table('users')
        ->whereRaw("users.id BETWEEN 1003 AND 1004")
        ->whereNotIn('users.id', [1005,1006,1007])
        ->whereIn('users.id',  [1008,1009,1010]);
    $query->where(function($query2) use ($value)
    {
        $query2->where('user_type', 2)
            ->orWhere('value', $value);
    });

   if ($user == 'admin'){
        $query->where('users.user_name', $user);
    }

终于得到了结果

    $result = $query->get();
