Save PDF-file to XML-file using php - php

Question

I have a form in which you can upload an image, which I then save to a folder on the server using php.
I'm storing the other data entered into the form in an xml-file, also using php. I now want to be able to store the pdf-file/the pdf-data in this xml-file as well for later use (the form acts as a template and I later want to store the entire information in another file and display it to the user).
I read about Base64 encoding etc. but I'm not sure if that applies to PDF-files as well because all I could find was how to do that for images or if there's an easier way to do it for my case?
Edit: Here's the HTML:
<form method="post" action="profile.php" enctype="multipart/form-data">
<input type="hidden" name="create_xml" value="true">
<label for="name">Name: </label><br>
<input type="text" name="name"><br>
<label for="email">E-mail: </label><br>
<input type="text" name="email"><br>
<label for="textbox">Write something: </label><br>
<textarea name="textbox" rows="5" cols="40"></textarea><br>
<label for="fileToUpload">Upload a PDF-file: </label>
<input type="file" name="fileToUpload" id="file-select">
<input type="text" name="filename" placeholder="Enter the name of your file"><br>
<input type="submit" value="submit" name="submit">
</form>
php that saves the data to the xml file:
if(isset($_POST['create_xml'])) {
$xml = new DOMDocument();
$newProfile = $xml->createElement('Profile');
$xml->appendChild($newProfile);
$name = $xml->createElement('Name', $name);
$newProfile->appendChild($name);
$email = $xml->createElement('EMail', $emailaddress);
$newProfile->appendChild($email);
$textbox = $xml->createElement('Text', $text);
$newProfile->appendChild($textbox);
$xml->formatOutput = true;
$xml->saveXML();
$xml->save($filename.".xml");
}

If you want to make xml at the time of insert data in DB:
if($this->input->post('submit')){
$name = $_POST['name'];
$email = $_POST['email'];
$filename = $_POST['filename'];
$year = gmdate("Y");
if($_FILES){
$_FILES['fileToUpload']['name'] = $files['fileToUpload']['name'];
$_FILES['fileToUpload']['type'] = $files['fileToUpload']['type'];
$_FILES['fileToUpload']['tmp_name'] = $files['fileToUpload']['tmp_name'];
$_FILES['fileToUpload']['error'] = $files['fileToUpload']['error'];
$_FILES['fileToUpload']['size'] = $files['fileToUpload']['size'];
$ext = pathinfo($_FILES['fileToUpload']['name'], PATHINFO_EXTENSION);
$mtime = uniqid(microtime());
$uniqueid = substr($mtime, 2, 8);
$pdfname = $uniqueid . '.' . $ext; // pdf file encrypt name here which need to save
move_uploaded_file($_FILES['fileToUpload']['tmp_name'], 'uploads/' . $pdfname);
}
//Your insert query here remember here you should add $pdfname as pdflink
// If successful insertion than
$xml = new DOMDocument();
$newProfile = $xml->createElement('Profile');
$xml->appendChild($newProfile);
$name = $xml->createElement('Name', $name);
$newProfile->appendChild($name);
$email = $xml->createElement('EMail', $email);
$newProfile->appendChild($email);
$textbox = $xml->createElement('Text', $filename);
$newProfile->appendChild($textbox);
$pdflink = $xml->createElement('Text', $pdfname);
$newProfile->appendChild($pdflink);
$xml->formatOutput = true;
$xml->saveXML();
$xml->save($filename.".xml");
}
