Php 如何在laravel中组合两个或多个变量

这里有一个例子

变量1：

$encodedtoday = MemberProfile::whereDate('created_at', '=', $today )
->where('encoded_by', 'Mark')->count();

变量2：

$encodedtoday = MemberProfile::whereDate('created_at', '=', $today )
->where('encoded_by', 'Michael')->count();

变量3：

$encodedtoday = MemberProfile::whereDate('created_at', '=', $today )
->where('encoded_by', 'John')->count();

我知道这可以在数组中完成。请让我看看

像这样试试：

$encodedtoday = MemberProfile::whereDate('created_at', '=', $today )
->whereIn('encoded_by', ['Mark','Michael','John'])->count();

$encodedtoday += MemberProfile::whereDate('created_at', '=', $today )
->where('encoded_by', 'Mark')->count();

$encodedtoday += MemberProfile::whereDate('created_at', '=', $today )
->where('encoded_by', 'Michael')->count();

$encodedtoday += MemberProfile::whereDate('created_at', '=', $today )
->where('encoded_by', 'John')->count();

希望这有帮助

像这样尝试：

$encodedtoday = MemberProfile::whereDate('created_at', '=', $today )
->whereIn('encoded_by', ['Mark','Michael','John'])->count();

$encodedtoday += MemberProfile::whereDate('created_at', '=', $today )
->where('encoded_by', 'Mark')->count();

$encodedtoday += MemberProfile::whereDate('created_at', '=', $today )
->where('encoded_by', 'Michael')->count();

$encodedtoday += MemberProfile::whereDate('created_at', '=', $today )
->where('encoded_by', 'John')->count();

希望这有助于您定义$encodedtoday=0； 然后继续为所有这些添加计数：

$encodedtoday = MemberProfile::whereDate('created_at', '=', $today )
->whereIn('encoded_by', ['Mark','Michael','John'])->count();

$encodedtoday += MemberProfile::whereDate('created_at', '=', $today )
->where('encoded_by', 'Mark')->count();

$encodedtoday += MemberProfile::whereDate('created_at', '=', $today )
->where('encoded_by', 'Michael')->count();

$encodedtoday += MemberProfile::whereDate('created_at', '=', $today )
->where('encoded_by', 'John')->count();

因此，$encodedtoday将有最终计数。

->where('encoded_by', 'John')->count();

因此，$encodedtoday将具有最终计数。

您可以为“按名称编码”创建一个数组，然后将条件传递到其中，如下所示：

$encoded_by = ['Mark','Michael','John'];
$encodedtoday = MemberProfile::whereDate('created_at', '=', $today)
->whereIn('encoded_by', $encoded_by)->count();
return $encodedtoday;

您的示例恰好可以通过查询生成器轻松解决。这是您拥有的唯一用例还是问题更一般？您的示例恰好可以通过查询生成器轻松解决。这是您拥有的唯一用例还是问题更一般？
