PHP - Php Save To File, Not Send To Headers

I would like to store PDF file into mysql (this part works) and then send it as email attachment and it should be retrieved from mysql table.

Here's the code I have for now, but what it gives me is 0bytes large PDF file
Saving PDF to mysql (it works), because size of blob in mysql table is OK.
$fp      = fopen('generated.pdf', 'r');
$content = fread($fp,filesize('generated.pdf'));
$content = addslashes($content);
fclose($fp);
$DB->Query('insert into pdf_files (pdf_file, name) values ("'.$content.'", "'.$name.'")');

And here's the mailing part

<?php
$query = "SELECT name, pdf_file FROM pdf_files 
$result = mysql_query($query) or die(mysql_error());
while ($row = mysql_fetch_array ( $result))
{

$fileContent =$row['pdf_file'];
$fileName=$row['name'];

} 

$fileatt = $fileContent; // getting file
$fileatt_type ="application/pdf"; //type of file
$fileatt_name = "attachment.pdf"; // name
$fileatt_size = $fileSize;

$email_from = "dont@have.it"; // mail from
$email_subject = "Testtt"; // subject
$email_message = "Testtt.<br>";
$email_message .= "Testtt.<br>"; // Message
$email_to = $mail_user; // users mail

$headers = "From: ".$email_from; 

$file = fopen($fileatt,'rb'); 
$data = fread($file,filesize($fileatt)); 
fclose($file); 

$semi_rand = md5(time()); 
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x"; 

$headers .= "\nMIME-Version: 1.0\n" . 
"Content-Type: multipart/mixed;\n" . 
" boundary=\"{$mime_boundary}\""; 

$email_message .= "Testtt.\n\n" . 
"--{$mime_boundary}\n" . 
"Content-Type:text/html; charset=\"iso-8859-1\"\n" . 
"Content-Transfer-Encoding: 7bit\n\n" . 
$email_message .= "\n\n"; 

$data = chunk_split(base64_encode($data)); 

$email_message .= "--{$mime_boundary}\n" . 
"Content-Type: {$fileatt_type};\n" . 
" name=\"{$fileatt_name}\"\n" .
//"Content-Disposition: attachment;\n" . 
//" filename=\"{$fileatt_name}\"\n" . 
"Content-Transfer-Encoding: base64\n\n" . 
$data .= "\n\n" . 
"--{$mime_boundary}--\n"; 

$ok = @mail($email_to, $email_subject, $email_message, $headers); 

if($ok) { 
echo "<font face=verdana size=2><center>Mail was sent</center>";

} else { 
die("Error!"); 
} 
?>

Hello, I am a newbie regarding PHP and have done mostly only front-end web design for a couple of years and recently started querying DB's and displaying the data, but now this is a new project.

1) I have an external application sending HTTP POST requests to a specific php page on my web server.
2) I would like to store each new POST in a MySQL table and sort the value of all header names in their designated columns and add the current timestamp as well.
The headers included are "X", "Z", "Player", "UUID"

my DB has the columns 'X', 'Z', 'Player', UUID', 'Timestamp'.

I've tested code snippets as the ones below, but fail to incorporate them in the bigger picture of what I'm trying to achieve.
This one saves the data into a CSV, but it rewrites the file, appending a new line would already be a big step forward.

<?php
// https://gist.github.com/magnetikonline/650e30e485c0f91f2f40

class DumpHTTPRequestToFile {

	public function execute($targetFile) {

		$data = sprintf(
			"%s %s %s\n\nHTTP headers:\n",
			$_SERVER['REQUEST_METHOD'],
			$_SERVER['REQUEST_URI'],
			$_SERVER['SERVER_PROTOCOL']
		);

		foreach ($this->getHeaderList() as $name => $value) {
			$data .= $name . ': ' . $value . "\n";
		}

		$data .= "\nRequest body:\n";

		file_put_contents(
			$targetFile,
			$data . file_get_contents('php://input') . "\n"
		);

		echo("Done!\n\n");
	}

	private function getHeaderList() {

		$headerList = [];
		foreach ($_SERVER as $name => $value) {
			if (preg_match('/^HTTP_/',$name)) {
				// convert HTTP_HEADER_NAME to Header-Name
				$name = strtr(substr($name,5),'_',' ');
				$name = ucwords(strtolower($name));
				$name = strtr($name,' ','-');

				// add to list
				$headerList[$name] = $value;
			}
		}

		return $headerList;
	}
}


(new DumpHTTPRequestToFile)->execute('./dumprequest.csv');

This snippet also seems to return the headers and their values but I don't know how to efficiently write and append it to a TXT or CSV, or preferably, directly into a MySQL database.

<?php
foreach (getallheaders() as $name => $value) {

    echo "$name: $value";
	echo "<br>";
}
?>

Any help towards storing the header values of HTTP POST requests into a database would be greatly appreciated!
Also, storing the body data in a separate column is optional, but nice to have.

I am confused why I am getting the following error and was wondering if I could get a 2nd pair of eyes..

Quick question for you guys.

I am collecting payment data for a product.

Is it possible to send data from my form via http directly into another payment form via the post http headers?

So say if i had all the details payment info and address info and i matched my form exactly to theirs. Is it possible to write a php script to send the data from my form directly to another websites form to make an order, say amazon or a big site like this?

?first_name=samuel&last_name=east&action=Submit

Any Help?

Thanks

How do I send multiple headers with this code?

Code: [Select]

<?php

$postdata = http_build_query(
    array(
        'var1' => 'some content',
        'var2' => 'doh'
    )
);

$opts = array('http' =>
    array(
        'method'  => 'POST',
        'header'  => 'Content-type: application/x-www-form-urlencoded',
        'content' => $postdata
    )
);

$context  = stream_context_create($opts);

$result = file_get_contents('http://example.com/submit.php', false, $context);

?>
