     * @description:  PHP file upload class
     * @requires:   PHP 4.1 or higher
     *
     * @changes:      v2.15  - Added Danish (da) error messaging
     * @changes:      v2.14  - Edited acceptable_file_types checks to be more lenient
     * @changes:      v2.13  - Added Spanish (es) and Norwegian (no) error messaging, converted all non-valid HTML language chars to named entities
     * @changes:      v2.12  - Added Finnish (fi) error messaging
     * @changes:      v2.11  - Fixed bug if $this->save_file::$path is ""
     * @changes:      v2.10  - Added var $path to class definition
     * @changes:      v2.9   - Updated error_message[5] for NL (Dutch)
     * @changes:      v2.8   - Cleaned up Italian error messaging (thanks to Maurizio Lemmo - http://www.tenzione.it/ )
     * @changes:      v2.7   - Added new error code [5] to save_file() method, fixed minor bug if unable to write to upload directory
     * @changes:      v2.6   - Added $this->acceptable_file_types. Fixed minor bug fix in upload() - if file 'type' is null
     * @changes:      v2.5.2 - Added Italian (it) error messgaing
     * @changes:      v2.5.1 - Added German (de) and Dutch (nl) error messgaing
     * @changes:      v2.4   - Added error messgae language preferences
     * @changes:      v2.3.1 - Bugfix for upload $path in $this->save_file()
     * @changes:      v2.3   - Initialized all variables (compatibale with PHP error notices)
     * @changes:      v2.2   - Changed ereg() to stristr() whenever possible
     *
     *
     * METHODS:
     *  uploader()    - constructor, sets error message language preference
     *  max_filesize()   - set a max filesize in bytes
     *  max_image_size()  - set max pixel dimenstions for image uploads
     *  upload()    - checks if file is acceptable, uploads file to server's temp directory
     *  save_file()   - moves the uploaded file and renames it depending on the save_file($overwrite_mode)
     * 
     *  cleanup_text_file() - (PRIVATE) convert Mac and/or PC line breaks to UNIX
     *  get_error()   - (PRIVATE) gets language-specific error message
     *
     * Error code: available in English (en), French (fr), German (de), Dutch (nl), Italian (it)
     *  [0] - "No file was uploaded"
     *  [1] - "Maximum file size exceeded"
     *  [2] - "Maximum image size exceeded"
     *  [3] - "Only specified file type may be uploaded"
     *  [4] - "File already exists" (save only)
     *  [5] - "Permission denied. Unable to copy file"

    /*
    <readme>

     fileupload-class.php can be used to upload files of any type
     to a web server using a web browser. The uploaded file's name will
     get cleaned up - special characters will be deleted, and spaces
     get replaced with underscores, and moved to a specified
     directory (on your server). fileupload-class.php also does its best to
     determine the file's type (text, GIF, JPEG, etc). If the user
     has named the file with the correct extension (.txt, .gif, etc),
     then the class will use that, but if the user tries to upload
     an extensionless file, PHP does can identify text, gif, jpeg,
     and png files for you. As a last resort, if there is no
     specified extension, and PHP can not determine the type, you
     can set a default extension to be added.
     
     SETUP:
      Make sure that the directory that you plan on uploading
      files to has enough permissions for your web server to
      write/upload to it. (usually, this means making it world writable)
       - cd /your/web/dir
       - chmod 777 <fileupload_dir>
      
      The HTML FORM used to upload the file should look like this:
      <form method="post" action="upload.php" enctype="multipart/form-data">
       <input type="file" name="userfile">
       <input type="submit" value="Submit">
      </form>


     USAGE:
      // Create a new instance of the class
      $my_uploader = new uploader;
      
      // OPTIONAL: set the max filesize of uploadable files in bytes
      $my_uploader->max_filesize(90000);

      // OPTIONAL: if you're uploading images, you can set the max pixel dimensions
      $my_uploader->max_image_size(150, 300); // max_image_size($width, $height)
      
      // UPLOAD the file
      $my_uploader->upload("userfile", "", ".jpg");

      // MOVE THE FILE to its final destination
      // $mode = 1 :: overwrite existing file
      // $mode = 2 :: rename new file if a file
      //           with the same name already
      //            exists: file.txt becomes file_copy0.txt
      // $mode = 3 :: do nothing if a file with the
      //           same name already exists
      $my_uploader->save_file("/your/web/dir/fileupload_dir", int $mode);
      
      // Check if everything worked
      if ($my_uploader->error) {
       echo $my_uploader->error . "<br>";
      
      } else {
       // Successful upload!
       $file_name = $my_uploader->file['name'];
       print($file_name . " was successfully uploaded!");
      
      }
