$variable = array('this' => 1,
                    'that' => 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);

foreach ($variable as $key => $value) {
    User::where($key, '=', $value);
}

一定要对子查询应用任何其他过滤器，否则or可能会收集所有记录。

$query = Activity::whereNotNull('id');
$count = 0;
foreach ($this->Reporter()->get() as $service) {
        $condition = ($count == 0) ? "where" : "orWhere";
        $query->$condition(function ($query) use ($service) {
            $query->where('branch_id', '=', $service->branch_id)
                  ->where('activity_type_id', '=', $service->activity_type_id)
                  ->whereBetween('activity_date_time', [$this->start_date, $this->end_date]);
        });
    $count++;
}
return $query->get();

你可以像这样在匿名函数中使用子查询:

 $results = User::where('this', '=', 1)
       ->where('that', '=', 1)
       ->where(
           function($query) {
             return $query
                    ->where('this_too', 'LIKE', '%fake%')
                    ->orWhere('that_too', '=', 1);
            })
            ->get();

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]
        ])

根据我的建议，如果你正在做筛选或搜索

那么你应该选择:

        $results = User::query();
        $results->when($request->that, function ($q) use ($request) {
            $q->where('that', $request->that);
        });
        $results->when($request->this, function ($q) use ($request) {
            $q->where('this', $request->that);
        });
        $results->when($request->this_too, function ($q) use ($request) {
            $q->where('this_too', $request->that);
        });
        $results->get();

使用Array的条件:

$users = User::where([
       'column1' => value1,
       'column2' => value2,
       'column3' => value3
])->get();

将产生如下查询:

SELECT * FROM TABLE WHERE column1 = value1 and column2 = value2 and column3 = value3

使用匿名函数的条件:

$users = User::where('column1', '=', value1)
               ->where(function($query) use ($variable1,$variable2){
                    $query->where('column2','=',$variable1)
                   ->orWhere('column3','=',$variable2);
               })
              ->where(function($query2) use ($variable1,$variable2){
                    $query2->where('column4','=',$variable1)
                   ->where('column5','=',$variable2);
              })->get();

将产生如下查询:

SELECT * FROM TABLE WHERE column1 = value1 and (column2 = value2 or column3 = value3) and (column4 = value4 and column5 = value5)
