Why does my file being downloaded have my page's HTML appended?

Update: Never mind. It was happening because it was adding the headers back. So I moved the php code separate from html and it worked. thanks guys

I am using the code below

 <?php 
    
        $target_path = "Files/";
        $target_path = $target_path . basename( $_FILES['decryptfile']['name']);
            
                        
                    $fp = fopen('Files/'.$_FILES['file']['name'], 'rb');
            header('Content-type: '.$_FILES['file']["type"]);                                                              
            header('Content-Disposition: attachment; filename="'.$_FILES['file']['name'].'"'); 
            header("Content-Length: " . filesize('decryptedFiles/'.$_FILES['file']['name']));
    
            
            fpassthru($fp);
            exit;
            die();
                
        
        
        
        
    ?>
    
    
    
    <form enctype="multipart/form-data" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST">
    Choose a file : <input name="file" type="file" /><br /><p>
    Start  process</a></center></p>
    <p><center><开发者_StackOverflow;input type="submit" value="File" /></center></p>
    
    </form>

My file contents are:

1234567890

when I download the file it shows

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>

</head>
  
    <form enctype="multipart/form-data" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST">
    Choose a file : <input name="file" type="file" /><br /><p>
    Start  process</a></center></p>
    <p><center><input type="submit" value="File" /></center></p>
    
    </form>
   

1234567890

Problem is that it appends (includes) the html of my web page to the file... how can I avoid that. thanks

Do a exit after fpassthru().

Also, you should look at the cleaner readfile().

If there's any content following the above code, you need to die(), or it will still be output as normal.
