How do I show data in php without using echo or print

Question

I would like to know if there's another way to do show data in client side, like laravel does using templates, by example;

In laravel we must to do it like this:

<?php

the result of  {{ $a }} + {{ $b }} is equals to {{ $c }}

?>

how could I do that but without using a framework?

ps: I can use echo, print, var_dump, etc. but I don't want to, I wish there's a different way, something more elegant.

除了回显和打印，您可以尝试在PHP中使用var_dump（）刷新所有变量
