PHP: Receiving blank email

Question

I used isset() function so that I will not receive the blank email. I can still receive blank emails.

Please see my code

Is !empty() better than isset() ?

What is the difference between the two?

Many Thanks

if (isset($_POST['name']) && isset($_POST['email']) && isset($_POST['phone'])){



$postcode = isset($_POST['postcode']) ? $_POST['postcode'] : "";
$name     = isset($_POST['name']) ? $_POST['name'] : "";
$email    = isset($_POST['email']) ? $_POST['email'] : "";
$phone    = isset($_POST['phone']) ? $_POST['phone'] : "";
$business = isset($_POST['business']) ? $_POST['business'] : "";

$to      = 'rme@btel.com';
$subject = "=?UTF-8?B?" . base64_encode('Message from BTelecom') . "?=";

$headers = "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html; charset=utf-8\r\n";
@$message = '<!DOCTYPE html><html><body>' .


'Post Code: ' . strip_tags($postcode) . '<br/>' .
'Email: ' . strip_tags($email) . '<br/>' .
'Name: ' . strip_tags($name) . '<br/>' .
'Phone: ' . strip_tags($phone) . '<br/>' .
'Business: ' . strip_tags($business) . '' .

    '</body></html>';
    $actual_link = "https://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
    $result = mail($to, $subject, $message, $headers);

}

`empty()` and `isset()` are not the same. Why the `@` before `$message`? — Spoody, May 17 '18 at 06:21
I don't know how to explain further... read the code part I mentioned in my comment. — Spoody, May 17 '18 at 06:23
@ suppresses the error and I don't see why you would want that — hungrykoala, May 17 '18 at 06:23

PHP empty function just checks the blank value while on other side isset checks for variable existence.
