返回没有空格的数据

Question

I am using Laravel 5.2. I am looking querying usernames with eloquent in order to create a unique profile page. The issue I am having is the usernames are returning with white space e.g. John Doe I need it to return with no white space like johndoe or JohnDoe. Thanks.

public function show($username)
{
    try
    {
        $user = str_replace(' ', '', User::wherename($username)->firstOrFail());
        dd($user);

    }
    catch(ModelNotFoundException $e)
    {
        return redirect()->action('HomeController@index');
    }
}

Answer 1

This can help -

str_replace(" ", "", "John Doe");

Or if there is multiple spaces (continuous) -

preg_replace('/\s+/', '', "John Doe");
