Laravel 8 Str::limit() {#collection-method}

Str::limit 方法将字符串以指定长度进行截断：

use Illuminate\Support\Str;

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

// The quick brown fox... 

您亦可通过第三个参数来改变追加到末尾的字符串：

use Illuminate\Support\Str;

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

// The quick brown fox (...)
