I think that prints value of $error variable with HTML tag in echo statement. Am I right?

$error = 'this is an error.';
...   
<?php
if (isset($error)) {
    echo "<p> {$error} </p>\n";
}
?>

But I don't know the difference between <p> {$error} </p> and <p> $error </p>.

there is no difference: `
$error
===
{$error}
` please read the informations on the links! – Sebastian Brosch Apr 05 '16 at 13:33
No difference, but if your variable is a array, use {$variable['item']} to print the value. – Maxi Schvindt Apr 05 '16 at 13:59
