Show blog post excerpt with Laravel
提问by 303K
I'm trying to show the excerptsfrom blog posts. I am able to do this with phpand mysql. However, I am wondering if there is a more 'friendly' way of doing this within the Laravel framework.
我正在尝试展示excerpts来自博客文章的内容。我可以用phpand做到这一点mysql。但是，我想知道在 Laravel 框架内是否有一种更“友好”的方式来做到这一点。
Thanks!
谢谢！

You can do it using the method words
您可以使用该方法来完成 words
Default is:
默认为：
words($value,$words = 100, $end='...');
You can implement it like this
你可以像这样实现它
Str::words($post->body);
Str::words($post->body,10); //will show first 10 words

Sorry I am very late but hope that it will help someone:
对不起，我来晚了，但希望它会帮助某人：
Using it like this may throw "Class 'Str' not found error":
像这样使用它可能会抛出“找不到类‘Str’错误”：
Str::words($post->body,10);
Use along with complete namespace, like this:
与完整的命名空间一起使用，如下所示：
\Illuminate\Support\Str::words($post->body, 10);
OR with dots:
或带点：
\Illuminate\Support\Str::words($post->body, 10,'...');
OR register the function as Facade in config/app.php, try adding it like this way:
或者在config/app.php 中将该函数注册为 Facade ，尝试像这样添加它：
'aliases' => [
...
'Str' => Illuminate\Support\Str::class,
...
]
And then use Str::any where!, and hence you are free you use: Str::words($post->body,10);
然后使用Str::任何地方！，因此您可以自由使用： Str::words($post->body,10);
Need short and neat solution, just use Laravel's str_limit()helper function:
需要简洁的解决方案，只需使用 Laravel 的str_limit()辅助函数：
str_limit($post->body, 10);
OR
或者
str_limit($post->body, 10,'...');
