Why is my form no longer showing up? - php

Question

I created a contact form in a PHP project and I have been trying to get the mail to send and in the process I have been altering some code such as removing my contact form. Now I re-added the form, but it does not display on the browser:
This is the actual file called contact.php:
<?php
define("TITLE", "Contact Us | MicroUrb");
include('includes/header.php');
/**
* PHPMailer Autoloader
*/
require '../vendor/phpmailer/phpmailer/PHPMailerAutoload.php';
/**
* Configure PHPMailer with your SMTP server settings
*/
$mail = new PHPMailer();
$mail->isSMTP();
$mail->Host = 'smtp.gmail.com';
$mail->Port = 465;
$mail->SMTPAuth = true;
$mail->Username = 'myemail#example.com';
$mail->Password = 'secret';
$mail->SMTPSecure = 'tls';
/**
* Enable SMTP debug messages
*/
$mail->SMTPDebug = 2;
/**
* Send an email
*/
$mail->setFrom('sender#gmail.com');
$mail->addAddress('recipient#gmail.com');
$mail->Subject = 'An email sent from PHP';
$mail->Body = 'This is a test message';
if ($mail->send()) {
echo 'Message sent!';
} else {
echo 'Mailer error: ' . $mail->ErrorInfo;
}
?>
