Laravel 4.2 blade: check if empty

In Laravel blade you can do: 

{{ $variable or 'default' }}

This will check if a variable is set or not. I get some data from the database, and those variables are always set, so I can not use this method.

I am searching for a shorthand 'blade' function for doing this:

{{ ($variable != '' ? $variable : '') }}

It is hard to use this piece or code for doing this beacuse of, I do not know how to do it with a link or something like this:

<a href="{{ $school->website }}" target="_blank">{{ $school->website }}</a>

I tried:

{{ ($school->website != '' ? '<a href="{{ $school->website }}" target="_blank">{{ $school->website }}</a>' : '') }}

But, it does not work. And, I would like to keep my code as short as possible ;)

Can someone explain it to me?

UPDATE

I do not use a foreach because of, I get a single object (one school) from the database. I passed it from my controller to my view with: 

 $school = School::find($id);
 return View::make('school.show')->with('school', $school);

So, I do not want to make an @if($value != ''){} around each $variable (like $school->name).

From Laravel 5.4, you can also use the @isset directive.

@isset($variable)
    {{-- your code --}}
@endisset

I wonder why nobody talked about $variable->isEmpty() it looks more better than other. Can be used like: 

@if($var->isEmpty())
    Do this  
@else
    Do that  
@endif

With php 7, you can use null coalescing operator. This is a shorthand for @m0z4rt's answer.

{{ $variable ?? 'default' }}

I prefer the @unless directive for readability in this circumstance.

@unless ( empty($school->website) )
    <a href="{{ $school->website }}" target="_blank">{{ $school->website }}</a>
@endunless

{{ ($school->website != '' ? '<a href="{{ $school->website }}" target="_blank">{{ $school->website }}</a>' : '') }}

change to

{{ ($school->website != '') ? '<a href="' . $school->website . '" target="_blank">' .  $school->website . '</a>' : '' }}

or the same code

{{ ($school->website != '') ? "<a href='$school->website' target='_blank'>$school->website</a>" : '' }}
