Can I use regex without a variable? Can I use flags?

[adjenks]

Regex with no variable:

    $r->addRoute('GET', '/{user|person}', 'get_user_handler');

Case insensitive flag:

    $r->addRoute('GET', '/{/user/i}', 'get_user_handler');

I tried both, they did not work. Am I doing it wrong?

My current workaround for both is to make a variable with a name I won't collide with, and use a 'mode modifier', eg.(?i), which I was unaware existed until this use case.

Example:

   $r->addRoute('GET', '/{junk_variable:(?i)user}', 'get_user_handler');

multiple route sections where you want to use regex force you to assign multiple junk variables though.

I didn't find an official solution, so if anyone needs it, here's a hacky option.

I solve it like this:

$r->addRoute('GET', '/{_-_:(?i)user}', 'get_user_handler');

// or in my case (uri wildcard)
$r->addRoute('GET', '/[{_-_:.*}]', 'get_user_handler');

case FastRoute\Dispatcher::FOUND:
  $handler = $routeInfo[1];
  $vars = $routeInfo[2];

  if (array_key_exists('_-_', $vars)) {
      unset($vars['_-_']);
  }

  // ... call $handler with $vars
  break;

btw: variable name in regular expression can contain - character and that is not a valid character for variables.

$r->addRoute('GET', '/[{_-_:.*}]', 'get_user_handler');

This is valid, but I cannot create an argument variable named $_-_. So it can be used as a name, but it cannot be used as a variable, so we can remove it from the $vars array.
