我在數(shù)據(jù)庫(kù)中存了一段示例代碼，如下所示：
<div class="container">
@foreach ($users as $user)
{{ $user->name }}
@endforeach
</div>
{{ $users->links() }}
數(shù)據(jù)庫(kù)內(nèi)容如下圖：
然后想通過(guò)blade模板完全顯示出來(lái)，就像很多教程一樣，把示例代碼顯示在網(wǎng)頁(yè)上。但是打開(kāi)網(wǎng)頁(yè)測(cè)試了一下，發(fā)現(xiàn)網(wǎng)頁(yè)是空白，只要把大括號(hào){{}}去掉或改成其他，就會(huì)正常顯示。有沒(méi)有什么方法可以把大括號(hào){{}}也直接顯示出來(lái)？
我又測(cè)試幾次，當(dāng)我這樣寫(xiě)的時(shí)候，
也同樣不會(huì)顯示示例代碼路由代碼如下：
Route::get('test', function () {
$data = '<pre><code>
<div class="container">
@foreach ($users as $user)
{{ $user->name }}
@endforeach
</div>
{{ $users->links() }}
</code></pre>';
return view('test', compact('data'));
});
test.blade.php代碼如下：
@extends('layouts.app')
@section('content')
{!! $data !!}
@endsection
app.blade.php代碼如下：

雙括號(hào)不寫(xiě)完整是可以顯示的如下
如果寫(xiě)完整后保存提交，編輯如下
再打開(kāi)顯示，全是空白，導(dǎo)航欄都沒(méi)有了
除非修改雙大括號(hào)，才會(huì)顯示出來(lái)
