Laravel 8 limit {#collection-method}

limit 方法用于将指定字符串切割为指定长度：

use Illuminate\Support\Str;

$truncated = Str::of('The quick brown fox jumps over the lazy dog')->limit(20);

// The quick brown fox... 

您亦可通过第二个参数来改变追加到末尾的字符串：

use Illuminate\Support\Str;

$truncated = Str::of('The quick brown fox jumps over the lazy dog')->limit(20, ' (...)');

// The quick brown fox (...)
