<?php

// If I copy and paste this unindented code...
$app->post('/admin/brands/{brandId}/unarchive', function (Application $app, Request $request, $brandId) {
$redirect = function () use ($app, $request) {
// TODO: Use URL Generator?
return $app->redirect($request->getBasePath() . '/admin/brands');
};
});

// It pastes as this... which is more or less exactly how it ends
// up looking if I just type it in and hit enter naturally...
$app->post('/admin/brands/{brandId}/unarchive', function (Application $app, Request $request, $brandId) {
        $redirect = function () use ($app, $request) {
// TODO: Use URL Generator?
            return $app->redirect($request->getBasePath() . '/admin/brands');
        };
    });

// What I expected is this...
$app->post('/admin/brands/{brandId}/unarchive', function (Application $app, Request $request, $brandId) {
    $redirect = function () use ($app, $request) {
    // TODO: Use URL Generator?
        return $app->redirect($request->getBasePath() . '/admin/brands');
    };
});

I had the same problem and I think I just found the configuration option to fix this.
Go to File -> settings and then select Code style -> PHP -> Tabs and Indents and set the Continuation indent to 0.
That has fixed the problem for me without breaking any other indentation (I'm still testing, but looks good by the moment).

@acelaya Thanks for the tip! I'll try this configuration for awhile. :)
