Files are corrupted when they are retrieved from database

Question

In my website, I want to allow the user to upload files (they will be stored in a database) and then allow them to download the uploaded files after that. The uploading process is done without errors and they are saved in binary.

The downloading process also works but the downloaded files are corrupted ! Any idea why?

The uploading code:

<?php require_once('Connections/databasestudents.php'); ?>
<?php

$fileName = $_FILES['file']['name'];
$tmpName  = $_FILES['file']['tmp_name'];
$fileSize = $_FILES['file']['size'];
$fileType = $_FILES['file']['type'];

$fp      = fopen($tmpName, 'r');
$content = fread($fp, filesize($tmpName));
$content = addslashes($content);

$studentId = $_POST['studentId'];
fclose($fp);

$query = "INSERT INTO file (studentId, fileName, fileType, fileContent ) ".
"VALUES ('$studentId', '$fileName', '$fileType', '$content')";

mysql_select_db($database_databasestudents, $databasestudents);
mysql_query($query) or die('Error, query failed'); 

header("Location: students.php");
die();

?>

The download code:

<?php require_once('Connections/databasestudents.php'); ?>
<?php
mysql_select_db($database_databasestudents, $databasestudents);
$query = 'SELECT fileName, fileContent, fileType, LENGTH(fileContent) as fileSize from file WHERE id="'. $_GET ['id'].'";';

$Recordset1 = mysql_query($query, $databasestudents) or die(mysql_error());
$row_Recordset1 = mysql_fetch_assoc($Recordset1);

$result = mysql_query($query);
$row = mysql_fetch_array($result, MYSQL_BOTH);
$size = $row['fileSize'];
$type = $row['fileType'];
$name =$row['fileName'];
$fileContent = $row['fileContent'];
echo $size . "". $type . " ". $name;

header("Content-length: $size");
header("Content-type: $type");
header("Content-Disposition: attachment; filename=$name");
echo $fileContent;

mysql_close();
?>

I've figured it out .. jus removing this line from the download code:

echo $size . "". $type . " ". $name;
