What is the difference between using echo in PHP files and in Smarty templates?

When using echo in PHP files, you can directly output variables or strings to the browser. However, when using Smarty templates, you need to use the {$variable} syntax to output variables within the template. This is because Smarty templates have their own syntax and processing engine separate from PHP. PHP code snippet: 

// Using echo in PHP file
$variable = "Hello, World!";
echo $variable;

// Using echo in Smarty template
$smarty->assign('variable', 'Hello, World!');
// In the Smarty template file:
{$variable}
