Enviando un correo electrónico con archivos adjuntos en PDF usando PHP

Question

Bien chicos, este es mi primer hilo, y lo he buscado en línea pero sin suerte. Estoy haciendo una pasantía y estoy trabajando en un proyecto que me obliga a crear una página web que genera un archivo pdf cuando un usuario envía su información. Tan pronto como un cliente hace clic en el botón de envío, 3 cosas tienen que suceder:

1. Almacenar la información a la base de datos (hecho),
2. Envía el personal de un correo electrónico con la nueva información del cliente (hecho), y
3. Envíe al cliente un mensaje de "mensaje de agradecimiento" con un archivo adjunto en PDF (no funciona).

Es decir, el cliente recibirá un correo electrónico, pero cuando él/ella abre el archivo PDF, me sale el siguiente mensaje de error:

"Acrobat podría no oen 'nombre_archivo', ya que es o bien no es un tipo de archivo compatible o porque el archivo se ha dañado (por ejemplo, se envió como un archivo adjunto de correo electrónico y no se decodificó correctamente) ... "

Tenga en cuenta que esta es mi primera vez haciendo un proyecto para crear un archivo PDF adjunto. Si alguien pudiera ayudarme a resolver este problema, sería genial. ¡Gracias!

Aquí está mi código:

<?php 
// once there are no errors, as soon as the customer hits the submit button, it needs to send an email to the staff with the customer information 
     $msg = "Name: " .$_POST['name'] . "\n" 
      ."Email: " .$_POST['email'] . "\n" 
      ."Phone: " .$_POST['telephone'] . "\n" 
      ."Number Of Guests: " .$_POST['numberOfGuests'] . "\n" 
      ."Date Of Reunion: " .$_POST['date']; 
     $staffEmail = "staffinfo"; 

     mail($staffEmail, "You have a new customer", $msg); // using the mail php function to send the email. mail(to, subject line, message) 

     //once the customer submits his/her information, he/she will receive a thank you message attach with a pdf file. 
     $pdf=new FPDF(); 
     $pdf->AddPage(); 
     $pdf->SetFont("Arial", "B", 16); 
     $pdf->Cell(40, 10, "Hello World!"); 

     // email information 
     $to = $_POST['email']; 
     $from = $staffEmail; 
     $subject = "Thank you for your business"; 
     $message = "Thank you for submitting your information!"; 

     // a random hash will be necessary to send mixed content 
     $separator = md5(time()); 

     // carriage return type (we use a PHP end of line constant) 
     $eol = PHP_EOL; 

     // attachment name 
     $filename = "yourinformation.pdf"; 

     // encode data (puts attachment in proper format) 
     $pdfdoc = $pdf->Output("", "S"); 
     $attachment = chunk_split(base64_encode($pdfdoc)); 

     // encode data (multipart mandatory) 
     $headers = "From: ".$from.$eol;
