Laravel 中视图中使用PHP代码

{{ $name }}
{{ date('Y-m-d H:i:s',time()) }}
{{ in_array($name,$arr)?'true':'false' }}
{{ isset($name)?$name:'default' }}
{{ $name or 'default' }}
原样输出 @{{ $name }}

@if ($name == 'hello')
    hello
@elseif($name == 'yes')
    yes
@else
    who
@endif
@foreach($student as $val)
  {{ $val->name }}
@endforeach
