How to attach .ics to email? - php

Question

I need to attach Outlook calendar file (.ics) to the email with mail function.
This is what I have now, but it is not working.
<?php
$firstname = $_POST["firstname"];
$lastname = $_POST["lastname"];
$email = $_POST["email"];
$companyname = $_POST["company"];
$file = "webinar-041016.ics";
$content = file_get_contents($file);
$content = chunk_split(base64_encode($content));
$EmailTo = "mail#mail.com";
$Subject = "New Webinar Registration";
// prepare email body text
$Body .= "Firstname: ";
$Body .= $firstname;
$Body .= "\n";
$Body .= "Lastname: ";
$Body .= $lastname;
$Body .= "\n";
$Body .= "Email: ";
$Body .= $email;
$Body .= "\n";
$Body .= "Company Name: ";
$Body .= $companyname;
$Body .= "\n";
$headers = 'From: mail#mail.com' . "\r\n" .
'Reply-To: mail#mail.com' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
$conf_subject = "Registration Complete ...";
$conf_body = "Dear " . $firstname . ",\n\nThank you..." ;
$conf_body .= "Content-Type: text/calendar; name=\"".$file."\"\r\n" ;
$conf_body .= "Content-Transfer-Encoding: quoted-printable\r\n";
$conf_body .= "Content-Disposition: attachment; filename=\"".$file."\"\r\n\r\n";
$conf_body.= $content."\r\n\r\n";
$conf_headers = 'From: web#mail.com' . "\r\n" .
'Reply-To: web#mail.com' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
// send email
$success = mail($EmailTo, $Subject, $Body, $headers);
$conf_mail = mail($email, $conf_subject, $conf_body, $conf_headers);
// redirect to success page
if ($success){
echo "success";
}else{
echo "invalid";
}
//Attached is an Outlook calendar invite so that you can plan your day accordingly.\n\n
?>
What should I do here? Is my encoding wrong?

You might have already seen this:
PHP Sending Mail
As a suggestion you might wanna have a look into PHPMailer which narrows down the work you have to do, to a single line of code:
$mail->addAttachment('/var/tmp/file.tar.gz');
