Laravel blade {{...}} vs <？=？>

Question

I am moving from cakephp to laravel and I would like to understand what is the advantage of {{ }} over the short php tags <?= ?>. I would guess the php tags are faster, not needing any processing by the template framework. I understood that {{ }} will do some escaping but when not necessary why using {{ }} and not <?= ?>. Also what is the advantage of @foreach and @if ... vs <?php foreach():?> ... <?php endforeach ?> and <php if():?> <?php endif;?>.

from Laravel docs:

Blade {{ }} statements are automatically sent through PHP's htmlspecialchars function to prevent XSS attacks. If you do not want your data to be escaped, you may use the following syntax:

Hello, {!! $name !!}.

Be very careful when echoing content that is supplied by users of your application. Always use the escaped, double curly brace syntax to prevent XSS attacks when displaying user supplied data.

Additionally if you are using blade template engine, it's like convention to use {{ }}
