Laravel 8 wrap() {#collection-method}

静态 wrap 方法会将给定值封装到集合中：

$collection = Collection::wrap('John Doe');

$collection->all();

// ['John Doe']

$collection = Collection::wrap(['John Doe']);

$collection->all();

// ['John Doe']

$collection = Collection::wrap(collect('John Doe'));

$collection->all();

// ['John Doe']Copy
