动态引用类属性

Question

for ($e = 1; $e <= 10; $e++)
{
    $edd = Setting::where('id', '=', $e)->update([
      'nama' => $request->nama1,
      'isi'  => $request->isi1,
    ]);
}

如何在for循环中动态引用类属性？我想在nama1对象上引用isi1和nama10最多isi10和$request。

Answer 1

for ($e = 1; $e <= 10; $e++)
{
    $edd = Setting::where('id', '=', $e)->update([
      'nama' => $request->{"nama$e"},
      'isi'  => $request->{"isi$e"},
    ]);
}

为了更具可读性，您可能希望这样做：

$request->{"nama{$e}"} // Notice the inner braces around $e
