Answer 1

To insert a PHP variable in a string you have to use curly brackets.

Like this:

<?php
$to_email = "receipient@gmail.com";
$subject = "Simple Email Test via PHP";
$body = "Hi,nn This is test email send by PHP Script";
$headers = "From: sender's email";

if (mail($to_email, $subject, $body, $headers)) {
    echo "Email successfully sent to {$to_email}..."; // <-- here the brackets
} else {
    echo "Email sending failed...";
}
