##The difference between {{}} and {!! !!} in Laravel

{{}} Supports escaping, a piece of html code is just output as an ordinary string; {!! !!} does not support escaping, and a piece of html code can be parsed normally.

What does it mean specifically? Let’s show the code:

Routing

Route::get(&#39;/demo&#39;, [&#39;uses&#39; => $namespacePrefix . &#39;BusinessController@demo&#39;, &#39;as&#39; => &#39;demo&#39;]);

Copy after login

Controller

public function demo()
{
    $address = "<span style=&#39;color:deeppink&#39;>我的家在哪遥远的北方</span>";
    return view(&#39;business.demo&#39;)->with([&#39;name&#39; => &#39;我叫张三&#39;,
        &#39;sex&#39; => &#39;我的性别男&#39;,
        &#39;address&#39; => $address,
    ]);
}

Copy after login

View layer code

<!doctype html>
<html>
<head>
    <meta charset="UTF-8">
    <meta name="viewport"
          content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>向视图传递值</title>
</head>
<body>
{!!$name.$sex. $address !!}-->不支持转义<br>
{{$name.$sex. $address}}-->支持转义（我理解未转换原来的意义）
</body>
</html>

Copy after login
