Laravel 8 isEmpty {#collection-method}

2021-07-19 10:32 更新

isEmpty 方法用于判断指定字符串是否为空：

use Illuminate\Support\Str;

$result = Str::of('  ')->trim()->isEmpty();

// true

$result = Str::of('Laravel')->trim()->isEmpty();

// false

以上内容是否对您有帮助：

← Laravel 8 isAscii {#collection-method}

Laravel 8 isNotEmpty {#collection-method} →
